    Abstract Iron-based 1111-type superconductors display high critical temperatures and relatively high critical current densities Jc. The typical approach to increasing Jc is to introduce defects to control dissipative vortex motion. However, when optimized, this approach is theoretically predicted to be limited to achieving a maximum Jc of only ∼30% of the depairing current density Jd, which depends on the coherence length and the penetration depth. Here we dramatically boost Jc in SmFeAsO1–xHx films using a thermodynamic approach aimed at increasing Jd and incorporating vortex pinning centres. Specifically, we reduce the penetration depth, coherence length and critical field anisotropy by increasing the carrier density through high electron doping using H substitution. Remarkably, the quadrupled Jd reaches 415 MA cm–2, a value comparable to cuprates. Finally, by introducing defects using proton irradiation, we obtain high Jc values in fields up to 25 T. We apply this method to other iron-based superconductors and achieve a similar enhancement of current densities.

    Abstract Given their excellent superconducting properties, REBa2Cu3Oy (REBCO)-coated conductors (CCs) are anticipated to be utilized in a variety of magnet applications. To further increase the critical current density Jc of these materials to levels needed for commercial applications, this study employs reel to reel (RTR) pulsed laser deposition (PLD) to fabricate REBCO+BaHfO3 (BHO) CCs. PLD creates BHO nanorods, which serve as flux-pinning defects. The material is subjected to O2+ irradiation to introduce more defects. The irradiation-induced defects serve as flux-pinning centers to the REBCO+BHO-nanorod CCs, increasing Jc along the c axis and over a wide range of magnetic-field angles compared with conventional REBCO+BHO-nanorod CCs. Both nanorods and irradiation-induced defects are demonstrated to be effective pinning centers in this material.

    Abstract Nanorods are a very effective pinning center in YBa2Cu3O7 films, and the vortex pinning mechanism should be understood to further improve the critical current density (Jc) in the nanocomposite films. Matrix defects are naturally formed during nanocomposite growth, and in this study the effect of matrix defects on the Jc in the YBa2Cu3O7 films containing nanorods is discussed. YBa2Cu3O7 + BaHfO3 and YBa2Cu3O7 + BaSnO3 films were prepared by varying the laser repetition frequency to control the matrix defects. All the films contained the nanorods. The YBa2Cu3O7 + BaHfO3 film of 2 Hz exhibits high Jc for magnetic field parallel to the c-axis (B//c) due to the nanorods and the isolated random point defects. In the YBa2Cu3O7 + BaHfO3 film of 10 Hz, while the short stacking faults and networked random point defects decreased the Jc for B//c, the short stacking faults improved the Jc for tilted magnetic field. In the YBa2Cu3O7 + BaSnO3 film of 10 Hz, the isolated random point defects improved Jc regardless of the magnetic field direction. While the ab-plane correlated defects are analyzed by the structural observation, the network or isolated nature of the random point defects can be discussed by the normal state resistivity. The matrix defects of YBa2Cu3O7 nanocomposite films should be designed considering the correlated/network/isolated nature which is determined by the morphology and defect concentration.

    For next generation of high field cryogen-free superconducting user magnets, we adopt a robust coil concept, which consists of two tapes co-wound in a face-to-back configuration, a fluorine-coated polyimide tape as the inter-bundle insulation and thin FRP plates glued on the coil edges. To validate our coil design, we investigated electromagnetic and current-voltage properties of 20-stacked REBCO pancake coils wound with Fujikura EuBCO tapes with the robust coil concept at 4.2 K under a background field of 14 T. The inner and outer diameters and total height of the coils are 68 mm, 266 mm, and 101 mm, respectively. The average of measured hoop and axial strain on the outermost winding at the mid plane of the 20-stacked coils were 0.23% and −0.15% respectively at a hoop stress of 370 MPa estimated by the BJR relation. The I - V properties of the coils showed no anomalous behavior up to 25 T totally generated by the coils and background field, suggesting that our coil structure has an advantage against large electromagnetic stress.

    Using a low-cost fluorine-free metal organic decomposition (FF-MOD) method, REBCO films with BaMO 3 (BMO, M = Zr, Hf) artificial pinning centers were fabricated. When M elements are conventionally added to the solution, the size of BMO formation depends on the growth conditions. But by adding preformed BMO nanoparticles, the size can be maintained on the nanometer order, meaning the nanoparticles act as effective pinning centers at low temperatures and magnetic fields. Adopting a polycrystallization sintering process enables the BaCO 3 to decompose completely and polycrystalline REBCO films to form prior to REBCO orientation. After final sintering, REBCO orientation can be achieved over a wide temperature range even with the addition of BMO nanoparticles. By utilizing preformed BMO nanoparticles and a polycrystallization sintering process, BMO doped GdBCO over 100 m-long tapes which have a thickness of more than 3 μm can be achieved. This is the first report of 120-meter-long artificial pinned REBCO tapes with I c exceeding 200 A/4 mm width at 77 K, self-field made by the FF-MOD method.

    The superconducting (SC) phase diagram in uranium ditelluride is explored under magnetic fields ($H$) along the hard magnetic $b$-axis using a high-quality single crystal with $T_{\rm c}$ = 2.1 K. Simultaneous electrical resistivity and AC magnetic susceptibility measurements discern low- and high-field SC (LFSC and HFSC, respectively) phases with contrasting field-angular dependence. Crystal quality increases the upper critical field of the LFSC phase, but the $H^{\ast}$ of $\sim15$ T, at which the HFSC phase appears, is always the same through the various crystals. A phase boundary signature is also observed inside the LFSC phase near $H^{\ast}$, indicating an intermediate SC phase characterized by small flux pinning forces.

    Superconducting properties were investigated in epitaxially layered films consisting of superconductor NbN and half-metallic Heusler alloy Co2MnSi (CMS). Temperature dependence of the electrical resistivity ρ( T) was measured by applying perpendicular magnetic fields to the surface of NbN/CMS films. With the increase of the CMS thickness dCMS, the upper critical field μ0 Hc2 decreased monotonically, but the superconducting transition temperature Tc had the minimum of 10.1 K at dCMS ≈ 5 nm. The Tc behavior was in qualitative agreement with the theory of the π-coupling. The pair-breaking parameter δ determined by the superconducting fluctuation theory took the maximum at dCMS = 3 ∼ 5 nm, which would be related to the minimum of Tc. The experimental results reveal that the superconductivity of the NbN layer in NbN/CMS films is affected by the interplay between the superconducting NbN layer and the half-metallic CMS layer.

    We recently proposed a robust REBCO HTS (RareEarth BaCuO) insert coil concept in the framework of a project to upgrade the 25 T Cryogen-Free Superconducting Magnet at the High Field Laboratory For Superconducting Materials to reach 30 T. In this article, the conductor consists of a two-tape bundle to mitigate the risks posed by local tape degradation. So-called edge impregnation is used to enhance the mechanical stiffness while reducing delamination risk, providing conduction-cooling capability at the same time. This insert is to be protected against the risk of thermal runaway simply by using dump resistor, thanks to an early detection concept. The different ideas forming the robust REBCO insert coil concept were tested successfully on various small scale prototypes. We report here their first implementation on a large-size insert coil, consisting of 20 stacked pancakes from the 30 T CSM upgrade insert. The mechanical behavior of the coil is modelled and validated with experiments. The thermal runaway detection setup is introduced. Its sensitivity and selectivity is discussed based on previous works on thermal runaway scenarios.

    Abstract We investigated the stress–strain relation and the applied strain dependence of critical current Icapp) of high-strength Bi2Sr2Ca2Cu3O10+δ (Bi2223) R&D tapes reinforced by ~100-μm-thick Ni-based alloy sheets with various pre- tensions Fpre applied during a lamination process. We confirmed that the thickening of Ni-alloy laminations is useful to enhance Young’s modulus compared with commercial tapes (≈30-μm-thick laminations). Icapp) decreases gradually and reversibly with applied strains εapp and then degrades irreversibly with larger tensile and compressive strains. The reversible strain regime tends to shift towards the tensile side with larger Fpre, indicating that application of large Fpre is effective to improve the reversible tensile strain limit. Observed Icapp) can be reproduced well by the model considering an εapp-linear critical current density, a cross-sectional strain distribution, and a Weibull-type distribution of filament damages. We clarified that different irreversible Icapp) degradations with large tensile and compressive strains can be understood by differences in the dimension and number of cracks and ruptures (tensile strains) and bucklings (compressive strains).

    Abstract The addition of artificial pinning centers has led to an impressive increase in the critical current density (Jc) of superconductors, enabling record-breaking all-superconducting magnets and other applications. The Jc of superconductors has reached ~0.2–0.3 Jd, where Jd is the depairing current density, and the numerical factor depends on the pinning optimization. By modifying λ and/or ξ, the penetration depth and coherence length, respectively, we can increase Jd. For (Y0.77Gd0.23)Ba2Cu3Oy ((Y,Gd)123), we can achieve this by controlling the carrier density, which is related to λ and ξ. We can also tune λ and ξ by controlling the chemical pressure in Fe-based superconductors, i.e., BaFe2(As1−xPx)2 films. The variation in λ and ξ leads to an intrinsic improvement in Jc via Jd, allowing extremely high values of Jc of 130 MA/cm2 and 8.0 MA/cm2 at 4.2 K, consistent with an enhancement in Jd of a factor of 2 for both incoherent nanoparticle-doped (Y,Gd)123 coated conductors (CCs) and BaFe2(As1−xPx)2 films, showing that this new material design is useful for achieving high critical current densities in a wide array of superconductors. The remarkably high vortex-pinning force in combination with this thermodynamic and pinning optimization route for the (Y,Gd)123 CCs reached ~3.17 TN/m3 at 4.2 K and 18 T (H||c), the highest values ever reported for any superconductor.

    Abstract In order to improve the electrical transport properties of REBa2Cu3O7−δ nanocomposite films, SmBa2Cu3O7-δ films with and without BaHfO3 nanoparticles were grown by chemical solution deposition (CSD), and their microstructural and transport properties were investigated in a detailed study using transmission electron microscopy and transport measurements in magnetic fields up to 24 T. The optimization process of the crystallization step (temperature and oxygen partial pressure) as well as an aging effect, which is due to the release of trapped fluorine, are described. Critical temperature and critical current densities surprisingly improve initially during the aging. Due to the complex microstructure, the additional BaHfO3 nanoparticles have only a positive effect at low magnetic fields for our samples.

    <title>Abstract</title>The fusion power density produced in a tokamak is proportional to its magnetic field strength to the fourth power. Second-generation high temperature superconductor (2G HTS) wires demonstrate remarkable engineering current density (averaged over the full wire), <italic>J</italic><italic>E</italic>, at very high magnetic fields, driving progress in fusion and other applications. The key challenge for HTS wires has been to offer an acceptable combination of high and consistent superconducting performance in high magnetic fields, high volume supply, and low price. Here we report a very high and reproducible <italic>J</italic><italic>E</italic> in practical HTS wires based on a simple YBa2Cu3O7 (YBCO) superconductor formulation with Y2O3 nanoparticles, which have been delivered in just nine months to a commercial fusion customer in the largest-volume order the HTS industry has seen to date. We demonstrate a novel YBCO superconductor formulation without the <italic>c</italic>-axis correlated nano-columnar defects that are widely believed to be prerequisite for high in-field performance. The simplicity of this new formulation allows robust and scalable manufacturing, providing, for the first time, large volumes of consistently high performance wire, and the economies of scale necessary to lower HTS wire prices to a level acceptable for fusion and ultimately for the widespread commercial adoption of HTS.

    Abstract We report the fabrication of 10 m-class (Ba, Na)Fe2As2 long round wires and coils using these round wires. Round wires are fabricated by powder-in-tube (PIT) method and hot-isostatic-press (HIP) technique. To increase Ic keeping the diameter of the wire constant, the cross section area of the superconducting core is enlarged by changing the dimensions of metal sheaths. At 4.2 K under a high field of 100 kOe, Jc of a short segment of HIP wire reaches 42 kAcm-2, which is comparable to the highest Jc of IBS round wires of 44 kAcm-2. Furthermore, Ic of the HIP wire at 4.2 K under 10 kOe and 100 kOe reaches 95 A and 54 A, respectively, which is about twice the value of the previous report. We also fabricated a small demonstration superconducting coil using 12.5 m long PIT wires by HIP method. Ic of the whole coil is ∼60 A under the self-field, and magnetic field at the center of the coil reaches 2.6 kOe. The coil generated the magnetic field of 43 Oe/A, which is almost consistent with the calculated field from the coil dimensions.

    Abstract Critical current density (Jc) in YBa2Cu3O7 films are improved by nanorods. Jc increases with increasing the nanorod content up to an optimum content, and decreases after exhibiting a maximum due to degradation of the nanorod structure. To overcome this optimization constraint, hybrid pinning consisting of multiple types of pinning centers was investigated. In the present study, Y2O3 nanoparticles were additionally introduced into the YBa2Cu3O7 films containing high density BaHfO3 nanorods to increase the effective matching field. As a result, the global pinning force maximum was shifted to high magnetic field, and the Jc was improved especially in high magnetic field. Thus, even in the case that the Jc improvement in the YBa2Cu3O7 + BaHfO3 was difficult by increasing the nanorod content, the Y2O3 addition successfully improved the Jc. This demonstrates that the hybrid pinning can overcome the optimization constraint for Jc in the YBa2Cu3O7 films containing nanorods.

    In this study, ultrasonic measurements were performed on a single crystal of cubic PrNi$_2$Cd$_{20}$, down to a temperature of 0.02 K, to investigate the crystalline electric field ground state and search for possible phase transitions at low temperatures. The elastic constant $(C_{11}-C_{12})/2$, which is related to the $\Gamma_3$-symmetry quadrupolar response, exhibits the Curie-type softening at temperatures below $\sim$30 K, which indicates that the present system has a $\Gamma_3$ non-Kramers doublet ground state. A leveling-off of the elastic response appears below $\sim$0.1 K toward the lowest temperatures, which implies the presence of level splitting owing to a long-range order in a finite-volume fraction associated with $\Gamma_3$-symmetry multipoles. A magnetic field-temperature phase diagram of the present compound is constructed up to 28 T for $H \parallel$ [110]. A clear acoustic de Haas-van Alphen signal and a possible magnetic-field-induced phase transition at $H \sim$26 T are also detected by high-magnetic-field measurements.

    We report the magnetocapacitance effect and the magnetostriction in the spin-crossover (SCO) complex [MnIII(taa)] (H3taa = tris(1-(2-azolyl)-2-azabuten-4-yl)amine). It is shown that huge enhancements of dielectric constant and lattice volume are caused by the field-induced SCO transition from the low-spin to the high-spin states in [MnIII(taa)]. In addition, the temperature-field phase diagram of the field-induced SCO in thermal equilibrium state is clarified up to 28 T. Our analysis suggests that a large magnetocaloric effect can also be caused by the field-induced SCO. These results indicate the possibility of multiple control of various material properties by the field-induced SCO.

    We report the effect of BaHfO<inf>3</inf>(BHO) introduction into SmBa<inf>2</inf>Cu<inf>3</inf>O<inf>y</inf>(SmBCO) films on the transport properties at artificial grain boundaries (AGBs) by comparing pure SmBCO and BHO-doped SmBCO films deposited on bicrystal substrates. Improvement of the critical current density (J<inf>c</inf>) at the AGB of BHO-doped SmBCO films was confirmed under the magnetic fields at which J<inf>c</inf>was restricted at the AGB. By investigating the superconducting properties and from TEM observations, we found that the in-field J<inf>c</inf>value for BHO-doped SmBCO films was improved through flux pinning of the Abrikosov–Josephson vortices by BHO nanorods.

    The dependence of BaMO3 (BMO: M = Zr, Sn, Hf) materials on reducing critical temperature (Tc) and lattice stress in BMO-doped SmBa2Cu3Oy (SmBCO) films is investigated by comparing the Tc and c-axis length of BaZrO3 (BZO)-, BaSnO3 (BSO)- and BaHfO3 (BHO)-doped SmBCO films with various BMO contents in this report. The Tc reduction rate against c-axis expansion was identical in all BMO-doped SmBCO films. It was revealed that the lattice stress on the SmBCO matrix in the BHO-doped SmBCO films was weaker than that in the BZO- and BSO-doped SmBCO films when comparing the SmBCO-BMO interfacial area dependence of the c-axis length of the SmBCO matrix. In addition, we confirmed that BHO was strongly strained by the SmBCO matrix as compared to BZO and BSO in SmBCO films. This is because the Youngs modulus of BHO was smaller than that of BZO and BSO. We conclude that restraining c-axis expansion is effective for keeping Tc high, and the BMO material with a small Youngs modulus can inhibit c-axis expansion.<tt> </tt>

    For the improvement and stable use of various superconducting applications using REBa2Cu3Oy (REBCO) coated conductors, the enhancement of the critical current density (Jc) in high magnetic fields is essential. It is known that BaMO3 (BMO; M = Zr, Sn, Hf) nanorods can improve the in-field Jc of REBCO films. Furthermore, the density and formation can be controlled by the deposition conditions such as deposition temperature and BMO content. In this study, our aim was to improve the Jc of SmBa2Cu3Oy (SmBCO) films in high magnetic fields. We tried to introduce high-density BaHfO3 (BHO) nanorods into SmBCO films by increasing the BHO content. We fabricated 2.3, 4.9 and 7.2 vol.% BHO-doped SmBCO films at the same deposition temperature, and compared the geometric formation of nanorods and flux pinning properties. From TEM observation, the densities of BHO nanorods increased with increases in BHO content, and the diameters of all nanorods were almost the same (i.e., approximately 12 nm). The highest density and matching field were 1711 /μm2 and 3.54 T in a 7.2 vol.% sample. The flux pinning force of the sample with a higher matching field was effective in higher fields in the magnetic field dependence of Jc. This was in good agreement with theories and many reports. In irreversibility field lines, a unique behavior, which probably originated in the thick diameters, was observed around the low magnetic field.

    We have proposed a low-temperature growth (LTG) technique which makes it possible to fabricate SmBa2Cu3Oy (SmBCO) films with c-axis orientation in a wide range of growth temperatures without the degradation of superconducting properties. In this study, using the LTG technique, we fabricated SmBa2Cu3Oy (SmBCO) films with BaHfO3 (BHO) nano-rods at low substrate temperatures using the pulsed laser deposition (PLD) method. The effect of low substrate temperatures on BHO nano-rods in SmBCO films are discussed in terms of their microstructures and superconducting properties. The nano-rods were observed clearly in transmission electron microscopic (TEM) images of the films. We found that the morphologies of the nanorods were small in diameter, had high densities and inclined along the c-axis of SmBCO. In the case of the substrate temperature of 750°C, the diameter and density of nano-rods with 2.7 vol.% BHO-doping were 5.7 nm and 2300 /μm2, respectively. The film showed high flux pinning force, Fp, of 25 GN/m3 (77 K, B//c) in a high field, 4 T. Furthermore, in the film, the angular dependence of Jc showed a broad peak at B//c, due to the flux pinning by nano-rods growing in various directions.

    Practical superconducting wires are designed with a composite structure to meet the desired engineering characteristics by expert selection of materials and design of the architecture. In practice, the local strain exerted on the superconducting component influences the electromagnetic properties. Here, recent progress in methods used to measure the local strain in practical superconducting wires and conductors using quantum beam techniques is introduced. Recent topics on the strain dependence of critical current are reviewed for three major practical wires: ITER-Nb&lt;sub&gt;3&lt;/sub&gt;Sn strand, DI-BSCCO wires and REBCO tapes.

    A high-strength pancake-coil structure called "Yoroi-coil" (Y-based oxide superconductor and reinforcing outer integrated coil), in which superconducting wire and the reinforcing outer plates of the coil withstand electromagnetic force, was developed for high magnetic field applications. The double-pancake (DP) coil of this coil structure was prepared and verified for durability against electromagnetic forces using the hoop stress test. The coil achieved 1.5 kA transporting at 4.2 K in an 8 T backup magnetic field without degradation of transport properties. Maximum hoop stress at the hoop stress test reached 1.74 GPa, based on the calculations. This result confirmed that the "Yoroi-coil" structure has the capability to withstand large hoop stress, which exceeds the tensile strength of Y-based coated conductors, not only owing to the strength of superconducting wire but also owing to the integration of the whole coil structure itself. Additionally, the strengthening effect of the structure was verified by analysis.

    This study investigates superconducting and mechanical properties of monolayer GdBa2Cu3Oy-coated conductor coils under large electromagnetic stress. We found that reversible superconducting properties can be achieved in the large hoop stress/strain states up to 1288 MPa/0.63% for the Hastelloy-outside-winding coil (coil A). This limit is larger than the results for the tensile test of the short sample. However, damage occurred near the current terminal at 640 MPa for the Hastelloy-inside-winding coil (coil B). It is considered that the degradation was due to the stress concentration at the edge of the current terminal. In the case of the Hasetelloy-inside-winding coil with a lap joint (coil C), the coil performance is limited by the shear stress of the lap joint.

    The effects of columnar defects on the critical current density (Jc) and electric (E) vs. current density (J) characteristics were investigated for a YBa2Cu3Oy thin film prepared using a pulsed-laser deposition method. The YBa2Cu3Oy thin film was irradiated with 200 MeV Au ions from a direction &theta;=8.8&deg;off the c-axis. Two peaks in the angular dependence of Jc were observed at the angles of &theta;=8.8&deg;and &theta;=90&deg;. These angles correspond to the directions of the columnar defect and intrinsic pinning, respectively. The E-J characteristics at various magnetic field angles can be described by the percolation transition model. The value of pinning parameter m increases at the angles of &theta;=8.8&deg;and &theta;=90&deg;. This result indicates that the efficiency of flux pinning is enhanced because fluxoids are effectively pinned by the columnar defects and intrinsic pinning or stacking faults in these directions.

    High-field magnetic torque measurement was carried out in the spin gap system (CH3)2CHNH3CuCl3. It was observed that the magnitude of the magnetic torque $\tau$ is almost zero until the critical field and then increases rapidly, which indicates the existence of magnetic quantum phase transition from the spin-gap phase to the field-induced magnetic ordered phase. From the temperature dependence of $\tau$, a cusplike minimum indicative of the Bose–Einstein condensation (BEC) of magnons was observed for $H\perp C$-plane, while a kink anomaly was observed for $H\perp A$-plane at the field-induced transition temperature. It was found that this difference in behavior between $H\perp A$-plane and $H\perp C$-plane can be interpreted as the breaking of the magnon BEC picture due to a rotational symmetry breaking. An additional anomaly was also observed in the field-induced magnetic ordered phase at the intermediate angle of the applied magnetic field in the $A$-plane and discussed in terms of spin-flop transition, spin-reorientation transition, and spin–lattice correlations. In order to investigate spin–lattice correlations in (CH3)2CHNH3CuCl3, we performed magnetostriction measurement and observed that magnetostriction appears with the disappearance of the spin gap.

    We have developed a cryocooled superconducting magnet for the 28 T hybrid magnet. The liquidhelium-free hybrid magnet has been designed to generate the magnetic field of 28 T that can be accomplished bycombining 9 T generation due to the cryocooled superconducting magnet with 19 T generation due to a water-cooledresistive magnet, which is inserted into a room bore of the superconducting magnet. In this work, we developed the 10T cryocooled superconducting magnet with the 360 mm room bore, whose inner coils are wound for employinghigh-strength Nb3Sn wires in consideration of large hoop stress. The liquid helium-free hybrid magnet has reachedthe generation of 27.5 T, which is greatly useful for high magnetic field science. The hybrid magnet also achieved thehigh magnetic-force field (B&middot;dBz/dz) of 4500 T2/m, which could levitate materials of small magnetic susceptibility such as an InSb semiconductor.

    More details Close

    We have reported high-Jc Sm1+xBa2-xCu3Oy (SmBCO) films prepared by a low-temperature growth (LTG) technique. The LTG-SmBCO films showed a Jc of 0.28 MA/cm2 (77 K, B//c, B=5 T). However, the Jc of these films in the magnetic fields above 5 T dropped and were lower than that of NbTi wire (4.2 K). In this study, we introduced nanoparticles with low Tc (low-Tc-nanoparticles) into LTG-SmBCO films to improve the Jc at the high magnetic field. The LTG-SmBCO + 1.4 vol.% nanoparticle film result in a Jc of 0.37 MA/cm2 (77 K, B//c, B = 5 T) and 0.10 MA/cm2 (77 K, B//c, B = 8 T). Furthermore, the Jc at 65 K in a field of 16 T (B//c) reached 0.05 MA/cm2. Elemental mapping clarified that LTG-SmBCO + 1.4 vol.% nanoparticle film had nanosized low-Tc particles with an x of 0.15-0.30 and low-Tc network with an x of 0.05-0.15, which were dispersed in the high-Tc matrix. We speculate that the Jc under high magnetic field conditions depends not only on the distribution and size of low-Tc regions, but also on the Sm/Ba composition within the low-Tc regions.

    Thermal runaway properties of Ag/Bi-2212 tape cooled by a cryocooler have been studied experimentally under the condition of magnetic fields up to 15T at 4K. To investigate the stability of the tape, Joule heating and a sample temperature were measured as a function of time at a fixed operating current. As a result, if cooling capacities are higher than Joule heating, it is found that thermal runaway current, Itr, is higher than critical current, Ic, which is defined by 1μV/cm. Furthermore, MRE (Minimum Runaway Energy) was measured as a function of operating current ratio, Iop/Itr, and the magnetic fields. The MRE decreased with increasing magnetic field in the same operating current ratio.

    In order to evaluate the distribution of flux pinning for a melt-textured grown bulk YBa2Cu3O7 under magnetic fields, the $E$-$J$ properties for samples prepared under various magnetic fields were measured. The measured $E$-$J$ properties were analyzed on the basis of a local $J_{\text{c } }$ distribution model proposed by Yamafuji and Kiss [K. Yamafuji and T. Kiss: Physica C 290 (1997) 9]. The distribution of local $J_{\text{c } }$ was found to narrow continuously with increasing magnetic field applied to the melt growth process, independent of the critical current density. The weak links at subdomain boundaries were considered to improve as a result of the change in crystallinity.

    We have designed and constructed a 15T cryocooled superconducting magnet with a vertical room temperature bore of 52mm. The main components of the magnet are four Nb3Sn superconducting coils, a NbTi superconducting coil, two pairs of bismuth-based oxide superconducting current leads (Bi2223 current lead) and two Gifford-McMahon (GM) cryocoolers. The coils were directly cooled down from room temperature to 3.6K in 114h by compact GM cryocoolers without liquid helium. The magnet generated a magnetic field of 15.1T at the center of the bore and was excited from 0 to 15.1T in 38min. The magnet succeeded in holding the field at 15.1T for 24h at the constant coil temperature of 3.8K.

    Critical current density properties for YBa2Cu3O7 films which have different pinning strengths were measured as a function of magnetic field, temperature or magnetic-field angle. We found that a kink anomaly appeared in the temperature dependence of critical current densities, Jc, and that the temperature at which the anomaly appeared depended on the extrinsic pinning strength. The magnetic field and angular dependences of Jc indicate that the anomaly is due to the crossover from intrinsic to extrinsic pinning. Using a competition model of intrinsic and extrinsic pinning, a kink anomaly is explained successfully.

    More details Close

    The Bi (2223) bulk current lead formed of a thin-walled sintered cylindrical tube has been developed and applied in a cryocooler cooled type superconducting magnet without using liquid helium. The critical current density of the bulk is over 1, 000A/cm2 under self magnetic field at 77K. The heat leakage from 60K to 10K of the bulk is estimated at 79.1mW and the bending strength of the Bi (2223) bulk current leads are 14-23MPa. The strength of the bulk are double or treble according to the Stycast coating on the bulk surface. Due to these superior properties, the Bi (2223) bulk current lead has been successfully used in a cryocooler magnet. The magnet system is running for 26, 000 hours without any degradation of the current lead.

    High performance of the critical current density Jc in Y1Ba2Cu3O7 films prepared by chemical vapor deposition has been demonstrated. The pinning mechanism in high-Tc superconducting oxides was explored from a viewpoint of the anisotropic behavior of Jc, and the global pinning force Fp was investigated in terms of the flux creep. It was found that the global pinning force on the basis of the flux creep theory well describes the Jc properties in CVD-Y1Ba2Cu3O7 films. The scaling in the form Fp∝(B/Bc2)1/2(1-B/Bc2)3/2 of the unrelaxed state which is not limited by the flux creep was presented.

    Y-Ba-Cu-O films were deposited on polycrystalline YSZ substrates by rf sputtering. Two types of targets were employed for the deposition. The as-sputtered films were insulators, but they became superconductive after being annealed in oxygen at 900°C for 3h. The plasma oxidation was performed in a mixture gas of Ar-50% O2 at 15mTorr by using the anti-sputtering in the same vessel as used for deposition; the rf power was 25W. The oxidation raises Tc and lowers the resistance ratio R (100K) /R (300K) of the films. The best films obtained so far exhibited a superconducting onset at 94K and zero resistance at 82K.<BR>Aging effect of the films at room temperature was also investigated. The higher Tc and the lower ratio R (100K) /R (300K) were maintained over a period of more than 30 days in dry air. This indicates that the impovement by the oxidation was not temporary.

    More details Close

    High Tc cuprate superconducting films, such as REBa2Cu3O7-x (RE=Y, Sm, Gd), REBa2Cu4O8 (RE=Y, Yb),(Hg, Re)Ba2CaCu2O6+x, (Hg, Re)Ba2Ca2Cu3O8+x, Bi2Sr2CaCu2O8 and Bi2Sr2Ca2Cu3O10, have been studied based on "atomic level control" including lattice strain control, carrier control, and nanostructure control, in order to simultaneously improve critical temperature Tc, irreversibility field Birr, and critical current density Jc of the films. We successfully fabricated high-performance cuprate superconducting films with higher Tc, Birr, and Jc on IBAD-MgO substrates.

    More details Close

    An MgB2 superconductor has the highest Tc among metallic superconductors. However, high Jc MgB2 wires are not currently obtained by major methods such as the power in tube method. Therefore, we prepared MgB2 thin films on Al tape substrates by EBE to fabricate high Jc MgB2 wires. The MgB2 thin films on Al tape substrates showed high Jc in Low magnetic fields for B//c. However, the Jc of the MgB2 thin film on Al tape substrate is suppressed drastically in high magnetic fields. In the field angular dependence of Jc, the peak appears at B//c due to c-axis correlated pinning centers. The magnetic field dependence of the reduced macroscopic pinning force density indicates that the additional pinning centers besides the grain boundary are found in the MgB2 thin films. These pinning centers are caused by the magnesium deficiency or the substitution of boron for magnesium site.

    We measured the transport critical current densities in high magnetic fields up to 17 T for Er123 films irradiated by 200MeV Au ion with the matching field of 0.1 T and 1 T along c-axis and 1 T for 23° tilting from c-axis. The angular dependence of critical current density suggests that the c-axis correlated pinning centers is effective even in much higher magnetic field than its matching field. In addition, we found that the peak of the flux pinning force density (Fp) curves related with the matching field of the columnar defects. The temperature scaling behavior of Fp in field along the defect direction was observed only in low field region below the matching field. Therefore, the c-axis correlated pinning is dominant in low field region. In higher magnetic field than the matching field, however, the c-axis correlated pinning works cooperatively with the background random pinning as well.

    We have designed and constructed a 15T cryocooled superconducting magnet with a vertical room temperature bore of 52mm. The main components of the magnet are four Nb3Sn superconducting coils, a NbTi superconducting coil, two pairs of bismuth-based oxide superconducting current leads (Bi2223 current lead) and two Gifford-McMahon (GM) cryocoolers. The coils were directly cooled down from room temperature to 3.6K in 114h by compact GM cryocoolers without liquid helium. The magnet generated a magnetic field of 15.1T at the center of the bore and was excited from 0 to 15.1T in 38min. The magnet succeeded in holding the field at 15.1T for 24h at the constant coil temperature of 3.8K.

    More details Close

    Magnetic field dependence of the critical current in high Tc grain boundary Josephson junctions(GBJJ)was studied to characterize the uniformity of the junctions,the effect of the anisotropy in high Tc superconductor.First we have observed the discrepancy between Fraunhofer-like patterns of the GBJJs and that of an ideal Josephson junction.The discrepancy was due to the nonuniformity of an artificial grain boundary as a junction barrier.Next we present an analysis of the anisotropic effect on the Fraunhofer-like patterns and show that the effect of longer magnetic field penetration depth;lambda c is observed only when the field is applied almost parallel to the a-b plane of GBJJs.In addition,when the misorientation angle θ was 36.8゜,the total curre nt was almost Josephson current.On the contrary,GBJJS with θ=24゜ w ere weak links containing strong coupling regions.

    In the first year of the project, the numerical model evaluating precisely the electromagnetic behavior of REBCO winding was developed, and experimental validations confirmed its accuracy on small scale test pancakes. In this last year detailed comparison were conducted on test coils to understand the relationship between current distribution dynamics, voltage, and generated field, which lead to the publication of a joint paper in collaboration with Grenoble CNRS. Then, the development was continued with the help of a more powerful workstation, which made it possible to simulate one half of a full-size very high field insert, like the one developed at HFLSM in the framework of the 30T CSM project. The accuracy of the model predictions on large scale systems will have to be confirmed once the magnet is tested in the next years, but already significant insights were obtained in terms of field homogeneity, field drift and AC losses for that magnet. This pave the way for an efficient control of the magnet, and the compensation of field drift in particular. In parallel, the project evolved toward calculating the consequences of inhomogenous current distribution in REBCO conductors in terms of mechanical stress. This development was triggered by rising concerns in the Applied Superconductivity community about the risk posed by stress concentrations in REBCO windings. The model developed in the course of this project could be readily adapted to provide insight on that topic. This development lead to an invited oral presentation at international conference CEC-ICMC in July 2021.

    Research and developments of a REBCO insert coil were performed aiming at a 50T class high field superconducting magnet. The robust coil structure with a mitigation of local degaradation, a current flow under local degaradation and avoiding burn-out were found. The mechanism of the robustness can be described by model calculations. As a reslut, we sucsessfully constract the basic technology for the 50 T-class superconducting magnet.

    In this research, we investigated an effect of new reinforcement coil structure “YOROI” in order to overcome a huge electromagnetic stress in the 50T-class high field superconducting magnet from both experimental and numerical simulation approaches. The model coil with the practical volume for insert coil in the high field magnet was made and tested in the high stress state. We found a drastic reduction of the hoop strsss from more than 1000 MPa to 200 MPa even for the practical volume reinforced structures. The obtained results were in agreement with the simulation results. Finally, we successfully design the inner most coil for the 50 T superconducting magnet within the induced hoop stress less than 500 MPa.

    Cubic cage-structured compound PrNi2Cd20 show no evidence for magnetic order in specific heat ang magnetization and suggest a non-Kramers Γ3-doublet crystalline electric field ground state. In order to investigate the CEF ground state and search for possible exotic phenomena such as quadrupolar order and multi-channel Kondo effect, we have performed ultrasonic measurements on a single crystal of PrNi2Cd20 and its reference materials (SmNi2Cd20, (Y,Pr)Ir2Zn20, RBe13 (R = Lu, Th, U), and UAu2Si2), down to 0.02 K up to 58 T, in collaboration with UC San Diego (USA), Dresden High-Magnetic Field Lab.

We found corroborating evidence for quadrupolar Kondo effect, and possible multipolar contributions on the low-temperature magnetic field-induced phase of these compounds.

    High strengthened CuNb/Nb3Sn monolithic conductor and equivalent cross-sectional 8-strand Rutherford cable conductor have been fabricated, and the critical current properties for react&wind processed coils with coil bending strain of ε=0.42% have been evaluated at 15 K and 4 T. It is found that the critical current properties of a Rutherford cable coil are superior to those of a monolithic coil in the react&wind method. We succeeded in developing a 25 T cryogen-free superconducting magnet composed of the world's first react&wind CuNb/Nb3Sn Rutherford cable 14.0 T cryogen-free superconducting magnet. Concerning quench characteristic and thermal stability of a high-Tc RE123 coil, we obtained that the higher temperature operation for a high-Tc RE123 coil is the suitable condition in case of occurrence of the normal transition.

    Based on TDGL simulations of critical current density Jc and unique flux-pinning modeling, optimum artificial pinning centers (APCs) of REBa2Cu3Ox (REBCO) superconducting films have been extensively studied. REBCO films were deposited on single crystal substrates or IBAD-MgO substrates by using PLD method which is available for making nanocomposite films. Several deposition techniques such as mixed target, low temperature growth and so on were used for controlling size and spatial distribution of APCs. Very high global pinning force density of 32 GN/m3 at 77 K and 1800 GN/m3 at 4.2 K were successfully attained, and simultaneously zero-field Jc might reach 30% of theoretical limit.

    In order to develop highly efficient energy materials, especially functional thin film, in this study we developed and investigated a thin film growth mechanism that produced thin films with "new functions". We achieved this by integrating the control of interface technology by(i) using an advanced thin film growth process that uses nano-technology,(ii) controlling the growth of interface,(iii) controlling the compositions and micro-structures of the films, and(iv) using multilayer technology. Furthermore, using these thin film growth processes and controlling of the interface, we intend to develop evaluation technology and composite technology for produced highly effective thermoelectric materials using nano-wire and oxide/non-oxide materials.

    Research subjective was to understand the basic mechanism for the critical current enhancement effect due to the applying repeated bending strain at room temperature fur pre-reacted NbaSn strands and to find the important guiding principle for the manufacturing process of NbaSn strand cables, employing pre-reacted NbaSn strands. To apply the critical current enhancement effect for NbaSn strands with the repeated bending strain treatment, a test oil was prepared by NbaSn strands reinforced with CuNb composite, and the critical current enhancement was confirmed in the test coil applied by a large hoop stress. The SEM observation was carried out for NbaSn strand-directional filaments etched out from the repeated-bending-treatment sample. It is found that the repeated bending treatment introduces micro-crack defects into NbaSn filament cores, and that such micro-crack defects do not increase until a tolerated strain limit of 0.8 %, in the case of NbaSn strands with. CuNb reinforcement in the outer portion. The NbaSn strands with and without the prebending treatment were measured by the neutron diffraction, which is a high resolution and high intensity powder diffractmeter at KEK in Tsukuba. The residual strains for the prepared NbaSn strands with and without the prebending treatment reveal the clear difference in the lateral direction between the two. We succeeded in indicating the residual strain reduction for the repeated bend NbaSn directly by the neutron diffraction. This means that the important understandings for the critical current enhancement elect of Nb_3Sn strands were obtained. The three + four (3+4) strand cable Consisting of three Nb_3Sn strands and four stainless steel strands were fabricated to develop new NbaSn stand cables applying the critical current enhancement effect It is found that the prepared 3+4 strand cable surely maintains such enhancement in the practical strand cabling process.

    本プロジェクトの最終年度にあたる平成17年度は,それまでの成果をふまえて,Coated Conductorの基板として用いられている一つであるISD(Inclined Substrate Deposition)法で作製されたMgO基板を用いて,強磁場中CVDでYBCO膜の作製を行い,その組織,配向性,超伝導特性の評価結果について示した.MgO基板では,成膜中における磁場の印加によって,面内配向性,臨界温度,不可逆磁場,臨界電流密度の向上が見られることが分かった.さらに,詳細な輸送特性を評価した結果,B//c方向に優位に働くc軸相関ピンが存在し,ゼロ磁場中で作製した膜においては,これまでに観測されたことのない,2つのc軸相関ピンが働いているpinned vortex liquid相が存在することが分かった.同じ条件で,磁場中で作製した膜では,そのうち高温にある相が消滅し,低温ではc軸相関ピンの向上が見られた.これは磁場によって,一方のc軸相関ピンが抑制され,もう片方が強調されることを示唆しており,粒界,双晶,さらにはc軸方向に揃った欠陥などが存在していると考えられる.また,ある条件で作製した試料では,これまでに報告されたどのRE123よりも高い不可逆磁場相が存在している兆候を見出した.その値は77.3K,B//cで19Tを超えると予想される.また,ISD-MgO基板では,c軸配向粒と25°傾角粒が混在した組織の膜が得られた.成膜中で磁場を印加するとc軸配向粒の結晶性は向上するが,25°傾角粒は劣化することが分かった.これらの結果から,現在,世界的に開発競争が繰り広げられているCoated conductorの特性が大幅に向上できる可能性を示したとともに,c軸相関ピンのメカニズムについての新たな知見が得られた.

    本研究費で購入した磁場中電気炉を金属材料研究所付属強磁場超伝導材料研究センターに既設の15T伝導冷却超伝導磁石と組合せ、これにすでに作製していた示差熱分析ユニットを挿入して、磁場中示差熱分析装置を完成させ、さらにLabView(ナショナルインストゥルメンツ社)上で動作する測定ソフトウエアを作製した。これにより15Tまでの高磁場中1200℃までの温度における示差熱分析装置が実現した。 開発した装置を用いて、磁場中の示唆熱分析を行い、溶融成長への磁場の影響を詳細に調べた結果、昇温過程における溶融温度が、磁場でまったく変化しない一方で、冷却過程では印加磁場の増加にともなって、結晶化に伴う発熱ピークが低温側にシフトすることが明らかとなった。さらなる詳細な実験により、磁場によって結晶成長速度が遅くなっていることが明らかとなった。ここで得られた結果は、以前から得られている組織変化や結晶性の向上などの結果を定性的に説明できる。 さらに、磁場中で溶融成長をさせた試料の磁束ピンニング特性をさらに詳細に調べるために、電流ー電圧特性を詳細に測定した。超伝導状態における電流ー電圧特性には局所的な臨界電流密度の分布の情報が含まれている。したがって、これを詳細に調べることによって、磁場によって磁束ピンニング特性がどう変化した理解できることになる。実験の結果、局所的な臨界電流密度の分布は、溶融時に印加した磁場が増大するにしたがって、狭くなることが分かった。これは、磁場によって磁束ピンニング特性そのものも影響を受けることを意味しており、今後の材料設計のパラメーターとして磁場が有用であることを意味している。

    A test coil employing CuNb/Nb_3Sn multifilament superconducting wire was prepared, and the cryogenic stability for the CuNb/Nb_3Sn coil was examined in liquid helium cooling and cryocooler cooling conditions. It is found that a minimum quench energy MQE in the cryocooling condition is reduced to 1/3 in comparison with the liquid helium cooling condition, and on the contrary a normal zone propagation velocity is enlarged by a factor of 3 to 4. These behaviors are dependent on the loading current ratio between the operation current and the critical current, and in particular the cryocooling condition reveals the strong dependence of the current ratio. Further, the CuNb/Nb_3Sn test coil fabricated by a react and wind technique was investigated in a large electromagnetic stress state. It is found that the test coil wound by the bending strain of 0.33% stood with the Hoop stress of 330Mpa, and that no degradation of the critical current for the test coil was observed. This surely results in confirmation of the patent for the CuNb/Nb_3Sn wire with reinforcing stabilizer. Finally, we started to construct the world's first cryogen-free hybrid magnet consisting of an outer cryogen-free compact wide bore superconducting magnet and an inner water-cooled resistine magnet. A cryogen-free 23 T hybrid magnet by the combination of a cryogen-free 8 T superconducting magnet with a 360mm warm bore magnet and a 15T water-cooled magnet will realize in near future.

    Superconducting properties under the large electro-magnetic stress state of Hoop or compressive stress were examined for a Ag-sheathed Bi2212 tape coil cowound with reinforcing tape. Further, the thermal stability characteristics for the test coil were also studied, aming to an application for a cryocooled superconducting magnet. Especially, we focused on the flux flow state of high temperature superconductors, and investigated the possibility whether such a stable flux flow resistivity without quenching could be applied as a new magnet technology or not. As a new attempt to overcome the large Hoop stress, the residual compressive strain for Bi2212 tape was added by tension-winding of Hastelloy alloy tape. This results in standing with the large stress of 270 MPa for Ag-sheathed Bi 2212 tape reinforeced with Hastelloy alloy tape. Moreover, the critical current characteristics in a transverse compressive strain state were measured for the Ag-sheathed Bi2212 test coil with Hastelloy reinforcing tape. An apparatus for measuring the transverse compressive strain effect in the critical current was installed into a cryogenfree superconducting magnet at the High Field Laboratory for Superconducting Materials. The transport current properties depending upon the reinforcement method were compared with each other, varing the applied magnetic fields up to 10 T.It was found that the Ic degradation of 40 % was occurred at the transverse compressive stress of 10 MPa for the Ag-sheathed Bi2212 tape coil without reinforcement, and that the same degradation corresponded to the reinforcing Bi2212 tape coil at 40 MPa. From the experimental results on the thermal stability for the Ag-sheathed Bi2212 tape, we can understand that the thermal stability in the cryocooling condition is closely related with the cryocooling power, and that the heating state above Ic is stabilized enough by keeping the cooling balance.

    High electromagnetic stress state is realized by transporting a large current in high fields for a double-pancake coil with a wide bore. We concentrate on a wide bore coil reinforced with highly strengthened Cu-50 Ag tape or Hastelloy tape using a co-winding technique for reacted Ag-sheathed Bi221 2 tape, in order to overcome about 300 MPa stress produced in a 30 T-class superconducting magnet. The mechanical properties for a high field superconducting magnet were evaluated in a large electromagnetic stress state using strain gauges. Two kinds of test coils reinforced with Cu-50 Ag tape or Hastelloy tape were made in a double-pancake shape with 11 X2 turns and 280 mm in diameter. Transport currents up to 500 A, which were above the critical current of 350 A, were applied for the test coil in liquid helium at 4.2 K and 10 T.The strains of 0.25 % and 0.22 % were applied at l=350 A for the Cu-50 Ag reinforcement coil and Hastelloy reinforcement coil, respectively. Hoop stress at 1=500 A corresponds to 262 MPa. It is found that the critical current does not degrade within strains of 0.16 %. This result indicates that a Hastelloy reinforcement Ag-sheathed Bi2212 coil overcomes electromagnetic stress up to 150 MPa.

    超伝導マグネットとしては22Tまでの磁場発生が従来型のNb_3Snを用いて実現されていて、超伝導特性的にはNb_3Snの限界に近いところにきている。この時の電磁力は150〜170MPa程度である。30T超伝導マグネットの電磁応力レベルは300〜350MPaと考えられる。 アメリカ合衆国や我が国の研究機関でNMR用の強磁場用高温超伝導マグネット開発研究が始まっている。NMRはまさに強磁場の必要性が明瞭で高分解能が得られるために、1GHz以上を目指して25T級超伝導マグネット開発用の小コイルテストが報告されている。しかし、これまでそのコイルに用いられた銀シースBi系高温超伝導線の機械的耐力はわずか80MPa程度でしかなく、強磁場発生の観点からはほど遠い研究状況にある。したがって、本研究のように実用的な高電磁応力状態を調べる意義は極めて大きい。 金研の強磁場センターに設置してある31Tのハイブリッドマグネットは外側が360mm直径の室温ボアに12Tを発生できる超伝導マグネットで、その内側に8MWで19Tを発生する水冷マグネットが組合されている。この内側の水冷マグネットを取り除くことによって大口径・強磁場超伝導マグネットとして用いることができる。AgシースBi系高温超伝導テープに補強と安定性を兼ねたAg-Cuテープを供巻きし、190MPaまでの高磁場応力試験に世界で初めて成功した。

    高T_c酸化物超伝導体の応用において最も重要なパラメ-タである臨界電流密度に関する研究を実施してきた。酸化物超伝導体の磁束ピンニングを解明するため,臨界電流の決定方法、組織とB_<c2>,J_cの関係、磁束ピンニングを検討した。以下に本年度の成果をまとめる。 (1)QMG法Y_1Ba_2Cu_3O_7バルクの磁化測定をB〓C,B⊥Cで23Tまで行った。4.2Kでは非常に多くの磁束ジャンプが出現した。断熱安定性の理論を用いると、磁束ジャンプを抑えるためには数10μmの極細化が必要である結果が得られた。さらに、強磁場までの磁化測定からは、QMG法バルクには弱結合性が存在していることが分った。 (2)CVD法とスパッタ法Y_1Ba_2Cu_3O_7膜におけるJ_cの角度依存性を比較検討した。組織は非常に異っているにもかかわらず、両者とも77Kでの強磁場中のJ_c特性が優れている。B_<c2>,J_cの角度依存性は、いずれも同じ磁束ピンニングのスケ-ル則とB_<c2>の角度依存性によって説明できた。 (3)磁束ピンニング力に対する磁束クリ-プの影響がどのようなものになるのかを検討した。高温領域では磁束クリ-プが顕著であるが、Kramer型のF_p曲線になる報告が多い。実測したJ_c値は磁束クリ-プの影響を受けていると考えて、F_p曲線にその影響による補正を行った。補正されたF_p曲線と実測されたKramer型曲線とを比較することで、磁束クリ-プが影響していないF_p曲線としてF_pαb^<1/2>(1-b)^<3/2>を得ることができた。これは、従来型のNbT〓線材にも観測されるF_p曲線であり、磁束ピンニング機構を考える上でピンニングの加算問題を検討しなければならないものと判断される。

    CVD法Y_1Ba_2Cu_3O_<7ーδ>は、磁場中の優れたJ_c特性を示す。磁束ピンニング機構を解明することを目的として、臨界電流密度の問題点を検討した。また、臨界電流密度と上部臨界磁場の角度依存性をそれぞれ測定した。 1.臨界電流の異方性と上部臨界磁場の角度衣存性を磁束ピンニングのスケ-ル則を通して関係づけることを試みた。上部臨界磁場の角度依存性はGLの有効質量モデルで比較的よく理解でき、特に抵抗遷移の中点での定義によるものは非常によく一致した。この有効質量モデルを磁束ピンニングに採りいれる試みは、J_cの角度依存性をかなり具体的に説明することができた。 2.しかし、酸化物超伝導体は磁束クリ-プの問題があり、臨界電流を決定するものはB_<c2>よりも小さいB^*_<c2>であると考えられる。B^*_<c2>は実質的にJ_c【approximately equal】Oを決定するもので、通常はグロ-バルピンニング力F_p対Bの関係から外挿的に求められるが、J_cの角度依存性のフィッティングパラメ-タとして考えた。その結果、抵抗遷移のR=Oでの定義によるB_<c2>よりもさらに小さなB^*_<c2>の角度依存性を改めて磁束ピンニングのスケ-ル則に採り入れるべきであることが分かった。すなわち、J_cの角度依存性はB_<c2>の角度依存性によって生じていると結論される。 3.C軸配向にa軸配向の結晶粒が混在する場合も異方性が変化する。応用上問題となっている酸化物超伝導体の強い異方性を小さくする目的で、a軸配向の結晶粒が混在する体積率とB_<c2>,J_cとの関係を調べた。その結果として、B_<c2>の異方性は小さくできる可能性があるが、異方性が小さくなるとJ_cも急激に小さくなることが分かった。
