    Two-dimensional superconductivity is primarily realized in atomically thin layers through extreme exfoliation, epitaxial growth, or interfacial gating. Apart from their technical challenges, these approaches lack sufficient control over the Fermiology of superconducting systems. Here, we offer a Fermiology-engineering approach, allowing us to desirably tune the coherence length of Cooper pairs and the dimensionality of superconducting states in arsenic phosphides As x P 1− x under hydrostatic pressure. We demonstrate how this turns these compounds into tunable two-dimensional superconductors with a dome-shaped phase diagram even in the bulk limit. This peculiar behavior is shown to result from an unconventional valley-dimensionality locking mechanism, driven by a delicate competition between three-dimensional hole-type and two-dimensional electron-type energy pockets spatially separated in momentum space. The resulting dimensionality crossover is further discussed to be systematically controllable by pressure and stoichiometry tuning. Our findings pave a unique way to realize and control superconducting phases with special pairing and dimensional orders.

    Abstract Unidirectional magnetoresistance (UMR) is an attractive magnetic-field sensing technique as it enables detecting the in-plane direction of the external magnetic field with a single element. However, the UMR amplitude is typically several orders of magnitude smaller than those of other directional magnetoresistances exhibited in ferromagnetic thin films, hindering sensing applications using the UMR. For a directional magnetic sensor using the UMR, the in-depth understanding of mechanisms of the UMR and its enhancement are highly desirable. In this study, the structural dependence of the UMR in Fe-Sn heterostructure devices is investigated. We find a weak dependence of the UMR on interface configuration in the oxide cap/Fe-Sn heterostructures on various oxide substrates. In contrast, the normalized UMR amplitude is enhanced by a factor of 27 with increasing the Fe-Sn layer thickness from 4.0 to 100 nm. These results suggest that the magnetothermal effect dominates the large UMR in the Fe-Sn heterostructure devices.

    Bardeen-Cooper-Schrieffer (BCS) superfluidity and Bose-Einstein condensation (BEC) are the two extreme limits of the ground state of the paired fermion systems. We report crossover behavior from the BCS limit to the BEC limit realized by varying carrier density in a two-dimensional (2D) superconductor, electron-doped layered material ZrNCl. The phase diagram, established by simultaneous measurements of resistivity and tunneling spectra under ionic gating, demonstrates a pseudogap phase in the low doping regime. The ratio of the superconducting transition temperature and Fermi temperature in the low carrier density limit is consistent with the theoretical upper bound expected in the BCS-BEC crossover regime. These results indicate that the gate-doped semiconductor provides an ideal platform for the 2D BCS-BEC crossover without added complexities present in other solid-state systems.

    <p>Electric double layer transistor (EDLT) has attracted attentions over the decade as a useful tool to induce and control fascinating many physical properties at two dimensional (2D) materials surface based on its giant capacitance. This paper highlights another aspect of EDLT: electrochemical reaction as a method to achieve ultrathin films. Precise tuning of reactivity of electrochemical etching between ionic liquid and solid surface makes it possible to peel off 2D materials layer-by-layer. This technique was applied to an iron-based superconductor FeSe in EDLT towards the observation of high temperature superconductivity in ultra-thin film form.</p>

    We made magnetization measurements on superconducting YBCO and BSCCO films with high c-axis orientation and found a universal dependence of normalized magnetization hysteresis ΔM/ΔM0 on normalized magnetic field H/H0 along the c-axis, where ΔM0 is the magnitude of hysteresis ΔM at H=0 and He is the "irreversibility field." This relation between ΔM/Δ M0 and H/H0 is excellently fitted by a single curve irrespective of temperatures and materials investigated. Except for H'-H0, ΔM/Δ M0 decreases exponetially with H/H0, while in the vicinity of H0 the data deviates from the exponential dependence. On the basis of the flux creep model, we succeeded in interpreting the universality by employing a logarithmic dependence of the effective pinning potential on current J at high density, which was recently proposed by Zeldov et al., and a linear J dependence at low density formerly proposed by Anderson and Kim.

    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.

    We prepared bulk nanostructured superconductors, which shows aperiodic nanostructures, by high pressure torsion (HPT) processing and measured critical temperature Tc. Tc increases after HPT in Nb, but decreases in V and Ta. The different property can be explained by the difference in the intensity and distribution of the disorder in nanostructures. It is also shown that by HPT processing, type I superconductor Ta is converted to type II superconductor, and that NbTi alloy can be prepared from mixed powder of Nb and Ti. Using the microscopic theory of superconductivity, we found that the critical temperature Tc increases with decreasing the size of nanostructured superconductors. For dirty nanostructured superconductors, Tc decreases for some distribution of impurities and increases for other distribution of impurities with increasing the impurity potential.

    We have investigated vortex states confined in small squares of superconducting thin films with strategically introduced antidots. Scanning SQUID microscope images allow us to trace how vortices are trapped in antidots in different vorticities. We obtained several novel findings of (1) unique configurations of singly and multiply quantized vortices, (2) configurational symmetry and stability of the vortex states imposed with antidots, including interstitial vortices between antidots. We also manipulated the vortex states by utilizing the field history and the pinning effect in antidots and succeeded in visualizing vortex and antivortex clusters.

    We studied magnetic properties of two dimensional electron systems at SrTiO3 (001) surfaces,which were induced by electric field in the electric double layer transistor (EDLT) device configurations. While SrTiO3 is a well-known nonmagnetic oxide in bulk, the surface electron system of it with the carrier densities higher than 0.15 per one unit cell area shows the anisotropic magnetoresistance and the planar Hall effects, which are usually observed in ferromagnetic thin films. Through the detailed measurements of magnetization and in-plane anisotropy of magnetotransports, controlled by the gate voltage in the EDLT devices, we found that the observed magnetic properties do not caused by the ferromagnetic order but results from the spin alignment phenomena with a special spin texture, originating from a Rashba-type spin-orbit coupling enhanced with multi-orbital hybridization effect in Ti-3d electrons.

    We have fabricated superconducting quantum-vortex based functional logic gates composed of micro-structured mesoscopic antidot squares, in which a pair of vortices is used as an information bit. We successfully induced the same number of quantum vortices in each quantum vortex cell and observed the initial state of the logic gate with the scanning SQUID magnetic microscope. Although the problem remains in the control of the logic state by a current pulse, our research findings are useful for vortex-based, prospective applications, including the vortex-based cellular automata.

    We have developed electric double layer transistor (EDLT) devices, which allows us a high density carrier accumulation exceeding the limit of all solid field effect transistors, taking the advantage of the ultrahigh electric field generated at the electrochemical interfaces. We applied this technique to a wide range of materials including bulk crystals, thin films, and nanodevices fabricated by an exfoliation method combined with electron beam lithography. We succeeded in electrical phase control of superconductivity, ferromagnetism, and Mott-Hubbard transitions in various materials, among which we were able to encounter novel phenomena which are impossible in conventional all solid field effect transistors. We also found novel functions of EDLTs, such as electrical control of spin polarization and flexible devices, all of which indicates that EDLT is an extremely powerful technique to further broaden materials science.

We also succeeded in measuring the two kinds of gap energies in Ba(Fe0.93Co0.07)2As2, which is related materials of MgB2.

    本研究の目的は、超伝導体Sの両側に強磁性体F、または強磁性体と常磁性体Nを接合させたトンネル接合デバイスを用いて、F層からS層ヘスピン配向準粒子を注入することにより、超伝導を制御し、FFLO状態を引き起こすことである。19年度は、La_<0.7>Ca_<0.3>MnO_3/Nb/Ag(F/S/N)接合(F/S間トンネルバリア層をしてSrTiO_3を使用)の作成条件を再検討し、その0.26Kでのスピン注入効果を調べた。 トンネルバリア層の成長温度を760℃まで下げることにより、良好なトンネル接合の作製に成功した。この試料では磁場中において観測されるトンネルコンダクタンスGの電圧V依存性が非対称性を示し、見積もられる注入電子のスピンの分極率が50%であった。さらにG-V特性を詳細に理論的解析することにより、Nbではトンネル過程におけるスピン-軌道相互作用が比較的大きく、これが超伝導制御の障害となるという知見を得た。 以上から本試料においてはゼロ磁場中での超伝導制御は困難と考え、試料に磁場(膜面平行)をかけ超伝導ギャップを小さくしたところでのスピン注入による超伝導制御を試みた。その結果5T以上の磁場中(臨界磁場6T)において、スピン注入により超伝導が破壊されることを示すG-V特性の発散的性質が観測された。この異常を詳細に調べると、GはVの上昇とともに一旦飛びのような不連続を示した後に発散するという、2段階的な転移を通して常伝導になることを見出した。一段目の転移は、BCS状態からFFLO状態への移り代りを示すものと推測されるため今後の更なる検討が必要である。 当初予定していたLa_<0.7>Ca_<0.3>MnO_3/Nb/CoFe(F↑/S/F↓)接合、Nbの代りにA1、SrTiO_3の代りにMgOを用いた研究に関しては、進展具合が遅れ達成されなかった。本研究結果を基に今後も続けていきたい。

    Amorphous W thin film (a-W) keeps a superconductivity down to the thickness of 1.2nm. Then this material is useful on the research of superconductivity of two dimensional disorder systems. In this research, two kinds of samples, Si/a-W/Si and a-W/Si multilayrs, were prepared and their superconducting characteristics were investigated. The following results were produced. 1.Observation of disorder induced Superconductor-Insulator (S/I) transition in Si/a-W/Si stucture We measured the critical temperatures for various a-W film thickness with d_W=1-10nm. In d_W*1nm, superconductivity disappears and T-dependence of sheet resistance R_<sq> follows to the exp (T^<-1/3>) 's law. In the dependence of critical temperature T_<co> upon normal R_<sq> for d_W*1.2nm, the superconductivity disappears when R_<sq> equals to the quantum sheet resistance h/4e^2. This system indicates a typical disorder induced S/I transition. 2.Kostelize-Thoughless (KT) transition in a-W/Si multilayrs KT-transition is the second phase transition where the vortex-antivortex pairs are induced near Tc by the thermal fluctuation of phase in order parameter. Due to the detail measurements of I-V characteristics at zero field, (1) the relation of KT transition and superconducting coupling between a-W layrs was investigated by the change of thickness of Si layr and (2) the vortex loop excitation at KT-transition was observed by controlling the number of bilayrs. 3.Observation of magnetic induced S-I transition in Si/a-W/Si structure. In the samples with W-thickness of 1.2-3nm, the field induced S-I transition was observed by the temperature dependence of sheet resistance. Whether such a transition is vortex to Bose glass one caused by the fluctuation of superconducting phase or not was studied by analyzing the data with the Fisher's scaling law.

    層状構造を持つ高温超伝導体では、混合状態において磁場をab面に平行付近にかけた場合、磁束線には強いピン止め(本質的ピニング)が働くことが理論的に指摘されている。しかし本研究者は、これまでYBa_2Cu_3O_<7-δ>(YBCO)膜の電流電圧(I-V)特性の異方性を測定し、少なくともグラス転移温度T_g近傍では本質的ピニングの影響は見られないことを明らかにしてきた。この矛盾を明らかにするためには、単なる電気抵抗やI-V特性ではわからない、磁束線がどの温度で生成され始め、どの様な構造で侵入し、運動するのかという問題を直接調べる必要ある。そこで、レーザーアブレーション法で作成したYBCO膜を用いて、磁場をab面内で電流方向(x方向)に対し45°回転し、c軸(z軸)方向にθ=5°傾けた状態でのI-V特性を測定した。この場合、磁束にかかるロレンツ力はF_L=-J×B〜(0,-JBsinθ,JBsin45°)で表され、磁束の運動v=(0,v_y,v_z)によって生じる電場はE=(-v_zBsin45°+v_yBsinθ,v_zBcos45°,-v_yBcos45°)となる。よって温度の下降とともに直線的な磁束線が生成される様子は、xとy方向の電場の比|E_y/E_x|が0から1となることで観測できる。さらに本質的ピニングが働きはじめ磁束が階段状になると、z(c軸)方向の運動が押さえられるため再びこの比が0になることが予測される。 実際にB=4,6,8Tの磁場中で実験した結果、どの磁場中においても|E_y/E_x|は温度の下降と共に、磁束グラス転移の臨界領域に入るとほぼ同時に有限な値を示し始め、T_gをmidpointとして1に転移した。これは磁束グラス転移と共に、直線的な磁束が生成されることを意味し、本質的ピニングの効果が現れないこれまでの結果とつじつまの合うものである。さらにグラス転移が真の超伝導転移であるという予測とも一致する。本研究では、この直線的な磁束が階段状に折れ曲がる現象は少なくとも50Kまで観測されなかった。

    The superconducting multilayr, Nb/Nb_<1-X>Zr_X (x=.5-.3), is known to show an upturn feature in the parallel upper critical field H_<c2//> (T) at the characteristic temperature T^+with decreasing T.This phenomenon occurs due to the shift of the nucleated position of the order parameterDELTA (r) from Nb to Nb_<1-X>Zr_Xlayrs. In this work, our aim is to investigate the vortex structure to understand the behavior of the localizedDELTA (r) in the mixed state of this system. For this purpose, we have measured mainly the critical current density Jc of Nb/NbZr (x=.5) as a function of the field H and the various angles between H and film plane. The mostly interesting feature is that the peak effect has been observed in Jc-H// curves in the region of T>T^+ (=0.7Tc) , in which DELTA (r) localizes in Nb-layrs. Then we have precisely measured the angular dependence of Jc (H) above and below the field at Jc-peak, Hp. From these investigations, we have found the pancake vortex structure in Hp<H<H_<c2//>and the stepwise vortex structure in H_<c1><H<Hp. On the other hand, in the region of T<T^+, two kinds of kink structure in Jc-H// curves were observed at fields H_<L1> and H_<L2> which were plotted around the extrapolated line from H_<c2//> (T) curve in the range of T>T^+. Furthermore, from the measured results of angular derivative of Jc in the vicinity of the parallel fields around H_<L1> and H_<L2> and the theoretical calculation concerning the free energy in the vortex state, we have exhibited the occurrence of the phase transition at these characteristic fields. Therefore, the possibikity of the pancake vortex state has been suggested in the region of H_<c2//>>H>H_<L1> and that of the stepwise vortex state has been done in the range of H<H_<L2>. The results of this work contribute to give the efficient information on the vortex pinning mechanism of High Tc superconductor with the layred structure.

    最近、酸化物高温超伝導体の超伝導混合状態での量子磁束線の特異な構造が問題になっている。磁場を CuO面に傾けて印加したとき量子磁束線が階段状に侵入する (a) stepwise-vortex や CuO面に垂直方向成分のみ量子磁束線として存在する (b) 二次元 pancake-vortex が提案されている。これは高温超伝導体の層状構造に原因した超伝導秩序パラメーター Δ(r)の変調によると考えられている。本研究では、超伝導転移温度Tcが等しく電子拡散係数の異なる超伝導体 Nb とNbZr を交互に人工的に積層した層状の多層膜超伝導体の混合状態における量子磁束線の構造についてしらべた。この系は膜面に平行な磁場中おいて上部臨界磁場の近傍で Δ(r) の局在中心が T〜0.7Tcより高温側で Nb層 にあり低温側でNbZr層にあることが得られている。 Δ(r)のそれぞれの変調状態での膜面と磁場方向が平行なときの臨界電流密度の磁場依存性を磁場の向きと電流の向きが互に (1)直角と (2)平行の場合しらべ、さらに(1)(2)について磁場・温度一定下で臨界電流密度の膜面と磁場方向の角度依存性をしらべた。この実験の結果から得られたNb/NbZr 多層膜系の混合状態での量子磁束線の状態から上記の(a)(b)の構造について知見がえられた。論文は雑誌Physica Cに掲載された。 つぎに、もう一つの多層膜超伝導体として超伝導金属Vと反強磁性金属 Cr を交互に(1120)Al_2O_3および (001)MgOの二種類の単結晶基板上にエピタクシャル的に積層した人工格子膜について転移温度、上部臨界磁場の温度依存性などの物性測定が行なわれた。今回はV層の膜厚を300A^^・に固定し、Cr層の膜厚をいろいろ変化させた人工格子膜について調べた結果、上部臨界磁場や転移温度の振る舞いが積層膜の結晶方位軸の相違に強く相関すること判明した。この結果についての理論的解釈は目下進行中である。1993年4月1日の物理学会春季年会(東北大)で発表した。
