Abstract Nd-Fe-B-based permanent magnets are widely used for energy conversion applications. However, their usage at elevated temperatures is difficult due to the relatively low coercivity (H_c) with respect to the anisotropy field (H_A) of the Nd₂Fe₁₄B compound, which is typically 0.2H_A. In this work, we found that the coercivity of an (Nd_0.8Dy_0.2)-Fe-B sintered magnet could reach 0.4H_A, which was twice as high as the H_c/H_A of its Dy-free counterpart. Detailed microstructural characterizations, density functional theory and micromagnetic simulations showed that the large value of coercivity, H_c = 0.4H_A, originated not only from the enhanced H_A of the main phase (intrinsic factor) but also from the reduced magnetization of the thin intergranular phase (extrinsic factor). The latter was attributed to the dissolution of 4 at.% Dy in the intergranular phase that anti-ferromagnetically coupled with Fe. The reduction in the magnetization of the intergranular phase resulted in a change in the angular dependence of coercivity from the Kondorsky type for the Dy-free magnet to the Stoner–Wohlfarth-like shape for the Dy-containing magnet, indicating that the typical pinning-controlled coercivity mechanism began to show nucleation features as the magnetization of the intergranular phase was reduced by Dy substitution.

Abstract In the long history of permanent magnet research for more than 100 years, three-dimensional magnetic microscopy has been eagerly awaited to elucidate the origin of the magnetic hysteresis of permanent magnets. In this study, we succeeded in observing the three-dimensional magnetic domain structure of an advanced high-coercivity Nd-Fe-B-based permanent magnet throughout the magnetic hysteresis curve using a recently developed hard X-ray magnetic tomography technique. Focused-ion-beam-based three-dimensional scanning electron microscopy was employed to study the relationship between the observed magnetic domains and the microstructure of the magnet for the same observing volume. Thermally demagnetized and coercivity states exhibit considerably different magnetic domain structures but show the same periodicity of 2.3 μm, indicating that the characteristic length of the magnetic domain is independent of the magnetization states. Further careful examination revealed some unexpected magnetic domain behaviors, such as running perpendicular to the magnetic easy axis and reversing back against the magnetic field. These findings demonstrate a wide variety of real magnetic domain behaviors along the magnetic hysteresis inside a permanent magnet.

Abstract Magnetic refrigeration (MR) is a key technique for hydrogen liquefaction. Although the MR has ideally higher performance than the conventional gas compression technique around the hydrogen liquefaction temperature, the lack of MR materials with high magnetic entropy change in a wide temperature range required for the hydrogen liquefaction is a bottle-neck for practical applications of MR cooling systems. Here, we show a series of materials with a giant magnetocaloric effect (MCE) in magnetic entropy change (-∆S_m > 0.2 J cm⁻³K⁻¹) in the Er(Ho)Co₂-based compounds, suitable for operation in the full temperature range required for hydrogen liquefaction (20-77 K). We also demonstrate that the giant MCE becomes reversible, enabling sustainable use of the MR materials, by eliminating the magneto-structural phase transition that leads to deterioration of the MCE. This discovery can lead to the application of Er(Ho)Co₂-based alloys for the hydrogen liquefaction using MR cooling technology for the future green fuel society.

More details Close

The coercivity mechanism of Nd-Fe-B thin film samples with and without Nd deposition was investigated by simultaneous chemical and magnetic imaging by means of X-ray magnetic circular dichroism-photoemission electron microscopy. The two Nd-Fe-B thin film samples exhibited almost the same surface morphology and magnetic domain patterns, but their coercive fields were quite different, being 0.98 T for the sample with Nd deposition and 0.55 T for sample without Nd deposition. The chemical distribution of Nd revealed that Nd aggregates with the average size of 130 nm exist, and the density in the Nd-deposited sample is much higher than that in the not deposited one. A comparison of the magnetic and chemical contrast images implied that the Nd aggregates act as domain wall pinning sites, indicating that the large coercivity difference in the Nd-Fe-B thin films would be attributable to the different density of wall pinning sites.

We successfully fabricated L2₁-ordered Mn₂VAl Heusler thin films and evaluated their ferrimagnetic properties by soft x-ray magnetic circular dichroism (XMCD). The buffer layers and annealing temperatures were varied to prepare the Mn₂VAl films. We discovered that Mn₂VAl could be ordered in an L2₁ phase well when it was deposited directly onto an MgO (001) single crystalline substrate. The maximum values of L2₁ and B2 long-range order parameters we obtained were about 0.5 for both phases for samples without a buffer layer, when substrates were heated at 500°C or 600°C. The saturation magnetization (M_s) for these samples was roughly 150 emu/cc. This is rather small compared to that expected from the ideal Slater-Pauling behavior, which might be due to the suppressed degree of L2₁ or B2 ordering. Ferrimagnetism in the Mn₂VAl, ferrimagnetic coupling between Mn and V moments was clearly observed by using the XMCD technique in well-ordered L2₁-Mn₂VAl film as has been predicted in theoretical investigations.

Spin polarization of Cu embedded in Fe₇₀Co₃₀ films has been investigated by means of transmission x-ray magnetic circular dichroism (XMCD). [Fe₇₀Co₃₀(d_FeCo) / Cu(d_Cu)]_n multilayered films were fabricated on Si-N membrane substrate, fixing total thickness of Fe-Co and Cu layers. Magneto-optical sum-rules were applied to the measured absorption and XMCD spectra to determine quantitatively the spin and orbital moments of Cu. With decreasing the Cu layer thickness, the spin moment of Cu increases but exhibits to be saturated about 0.1 μ_B / atom. The small value of spin moment (0.1 μ_B), comparing to that of the 3d transition metals such as Fe and Co, implies that only the top part of 3d down-spin band of Cu is unoccupied in these specimens.

More details Close

Chiral spin textures at the interface between ferromagnetic and heavy nonmagnetic metals, such as Neel-type domain walls and skyrmions, have been studied intensively because of their great potential for future nanomagnetic devices. The Dyzaloshinskii-Moriya interaction (DMI) is an essential phenomenon for the formation of such chiral spin textures. In spite of recent theoretical progress aiming at understanding the microscopic origin of the DMI, an experimental investigation unravelling the physics at stake is still required. Here, we experimentally demonstrate the close correlation of the DMI with the anisotropy of the orbital magnetic moment and with the magnetic dipole moment of the ferromagnetic metal. The density functional theory and the tight-binding model calculations reveal that asymmetric electron occupation in orbitals gives rise to this correlation.

MCD measurement in extended X-ray absorption fine structure (EXAFS) energy range gives us information on the pair distribution of spin-polarized scattering sites around an absorption atom. Magnetic EXAFS at the Fe K-edge is presented for DyFe_2 powder and an Fe thin film, and the local magnetic structures are analyzed from the spectra. The positions and signs of peaks in the imaginary part of Fourier-transformed magnetic EXAFS agree well with those of conventional EXAFS for the iron thin film. In order to derive a ferrimagnetic coupling of spin moments between Dy and Fe from magnetic EXAFS spectra, the function σ(r) was defined as the difference between the absolute values of Fourier-transformed EXAFS functions for positive and negative helicities of circularly polarized X-rays. σ(r) accurately described the distribution of the spin polarization and its sign in ferrimagnetic DyFe_2.

More details Close

Chiral spin textures at the interface between ferromagnetic and heavy nonmagnetic metals, such as Neel-type domain walls and skyrmions, have been studied intensively because of their great potential for future nanomagnetic devices. The Dyzaloshinskii-Moriya interaction (DMI) is an essential phenomenon for the formation of such chiral spin textures. In spite of recent theoretical progress aiming at understanding the microscopic origin of the DMI, an experimental investigation unravelling the physics at stake is still required. Here, we experimentally demonstrate the close correlation of the DMI with the anisotropy of the orbital magnetic moment and with the magnetic dipole moment of the ferromagnetic metal. The density functional theory and the tight-binding model calculations reveal that asymmetric electron occupation in orbitals gives rise to this correlation.

We have studied the synchrotron X-ray magnetic circular dichroism (XMCD) measurement techniques using the nano-focused X-ray beam and the application to magnetic thins films. The time resolved XMCD signals have been successfully observed for the local area of about 100 nm in a Co/Pt multilayered film, where the applied magnetic fields were generated and synchronized with the pulsed X-rays. As a further advanced technical challenge, we have developed a scanning probe microscope (SPM) measurement technique combined with the synchrotron soft X-rays, which is so called SR-SPM. In the SR-SPM apparatus equipped with an X-ray focusing unit using a Fresnel zone plate, the higher density soft X-ray beam of about 1000 times compared to the previous studies irradiates the sample surface just below the SPM needle. XMCD signals from permalloy dots of the magnetite has been successfully recorded using the SR-SPM system with the special resolution of about 70 nm.

We have developed neutron and X-ray techniques in pulsed magnetic fields and have succeeded in combined them with ultra-low reduced temperature. The direct observation of order parameters and the electronic states by neutron and X-ray enables us to solve important long-time remaining problems such as the high field phases in U-intermetallics, valence state transition in Eu-ternary compounds, spin nematic phase in quantum spin chain and re-entrant transitions in multiferroics. We have also opened new paradigm such as X-ray free electron laser experiments in pulsed high magnetic fields, which uncovered the new three dimensional charge density wave in high-Tc superconductors. Our concept is now spreading over other areas such as spectroscopy, THz-ESR and particle physics. The present research has made our leading status in the area of high magnetic field quantum beam science more solid and has contributed much for the development in this and related areas.

High magnetic field x-ray magnetic circular dichroism apparatus in conjunction with a 40 T pulse magnet and a soft x-ray absorption spectroscopy has been developed for magnetic investigations of underlying microscopic mechanisms of electromagnetic effects. By applying the world first novel apparatus to multiferroic systems, we succeeded in observations of valence specific magnetizations of di and tri-valence irons of LuFe2O4, determinations of spin and orbital magnetic moments of Fe(III) in CuFeO2 and element specific magnetic analyses of Tb and Mn in TbMnO3.

We have successfully developed a new experimental technique of soft X-ray magnetic circular dichroism(XMCD) under pulsed high magnetic fields for the first time. The maximum magnetic field of 30 T has been achieved, which greatly exceeded the previous maximum field of 10 T generated by means of superconducting magnets. By applying the present technique, we can measure the partial magnetization originating from individual elements in alloys and compounds. The high-magnetic-field soft XMCD experiments have widely been applied to studies on a magnetic-field-induced valence transition material, a meta-magnetic material, rare earth based permanent magnets, and exchange bias film, so far.

A correlation between uncompensated (UC)antiferromagnetic (AF)spins and exchange bias (E. B.)strength was investigated for Mn_<74> Ir_<26>/Co_<100-x> Fe_x bilayers. The E. B. strength had a maximum at x=25 at.%, and the x-ray magnetic circular dichroism of Mn, representing the UC-AF spins, changed systematically in sign and magnitude with respect to x. A linear correlation was found between the E. B. strength and the root mean square magnitude of the UC-Mn spins. The hidden parameter connecting these two quantities might be exchange coupling energy at the hetero-interface, which varies as a function of the ferromagnetic layer composition. Based on the above findings, we succeeded to induce large (> 1. 2 erg/cm^2)E. B. strength on L1_2-Mn_3Ir/Co_<65> Fe_<35> bilayers with inserting an ultra-thin Co-Fe layer which induces large Mn-XMCD.

We have developed APD (Avalanche PhotoDiode) photon counting system for soft x-ray experiments at SPring-8. APD detectors for hard x-ray are widely used at synchrotron radiation facilities taking advantages of the high time-resolution and the wide dynamic-range. However, the present APD doesn't cover soft x-ray region. The purpose is to develop a new APD detector especially for soft x-rays, where the sensor has to be installed in ultra high vacuum. The lower noise level and the higher gain are required as the technical subject to achieve in the development. We have succeeded in detecting the soft x-rays and have observed x-ray bunch structures of synchrotron radiation, and a soft x-ray magnetic circular dichroism measurement.

We have successfully constructed pump&probe time-resolved photoemission electron microscope system (TRPEEM) at the soft-x-ray beamline of SPring-8. Combining TRPEEM with magnetic circular dichroism effect in absorption spectra, dynamics of the vortex structure of small magnetic dots could be observed in sub nsec regime in respond to magnetic field pulse. The interaction effect between the neighboring dots was also observed. Further, dynamical observation against the electric field pulse and laser beam pulse also became possible.

本研究はSPring-8BL25SUに設置した電磁石軟X線MCD装置に本補助金にて追加整備した蛍光収量法、および、透過法によるMCD測定機能を用いて進められた.実験装置の高度化を伴うMCDの手法開発を進めることにより、従来の磁気測定手法では成し得なかった新しい切りロで新規性の高い磁性材料の磁気特性について研究を行った.H19年度の装置高度化として、軟X線CCDを利用した蛍光収量法によるMCD測定を可能にした(SPring-8実験課題2007A1931).一方、東北大(角田准教授)と進めてきた巨大交換磁気異方性を有するMnlr/CoFe二層膜の界面磁性研究では、Mnの非補償スピンが反強磁性と強磁性界面付近に選択的に誘起される事実を透過MCD実験により明らかにした(JAP101,09E510(2007)).さらに、強磁性層(FeCo)におけるFeとCoの組成比を変化させると、交換異方性エネルギー(J_k)とMCD強度に比例関係が成立することを見出した(論文準備中).また、希土類内包フラーレンの磁気特性解明のためのMCD実験は、名古屋大の篠原教授との共同研究として進められ、Er,Gd内包フラーレンの他、Gd内包フラーレンをカーボンナノチューブ内に取り入れた、いわゆる、Gdピーポットの磁気特性(常磁性帯磁率、ワイス温度)を明らかにした(Phys.Rev.B76,172409(2007)andJ.Phys.ChemC112,6103(2008)).以上の成果の他にも、Auの傾斜基板上に成長させたFeのナノワイヤーに関するMCD実験等でも成果(Phys.RevB75,245423(2007))を得ており、本研究課題によってMCDによるナノ材料を中心とした新規磁性体の磁気特性研究を加速的に推し進めることに成功した.

Energy spectra of the X-ray emitted via the second order photo-excitation process give quite valuable information on a selected element which directly reflects ground states and excited states of electrons. This type of spectroscopy for inelastic scattering x-rays is named X-ray Emission Spectroscopy (XES). The objective of the present project is to develop the methodology of the spin-dependent magnetic circular dichroism XES (MCD-XES) and the application to transition metals and rare earths. The most remarkable achievement of the present study is that very precise MCD-XES spectra were obtained and the results were quantitatively examined comparing with the theoretical calculations, which for the first time enabled an appropriate interpretation of the origins of the MCD effect and was published in Physical Review. In order to construct the XES beam line at SPring-8, the measuring apparatus and various testing experiments were made by the cooperation with the group of Tohoku University. And the methodologies of the measurements and the analyses for the XES including MCD-XES have been established. Among them, the development of "Lifetime-broadening-suppressed/free XANES" is especially important, which supports the wide development of the applications of MCD-XES.

本研究は、Nd-Fe-B系薄膜磁石をはじめとする希土類-遷移金属磁性体について、硬X線MCDを用いた元素選択磁気ヒステリシス(ESMH : Element Specific Magnetic Hysteresis)をSPring-8において測定し、元素選択磁化測定技術と解釈を発展させること、さらに、硬X線ESMHと通常の磁気ヒステリシス曲線とを比較して、(1)硬X線ESMHの特徴、問題点についての知見を得ること、(2)Non-collinear磁気構造(希土類と遷移金属の磁気モーメントが平行に揃わない磁気状態)における、希土類と遷移金属の磁気モーメントの挙動分離を具体的な目的とした。この計画で硬X線を用いることを優先した理由は、次の[1],[2]の理由による。[1]軟X線は試料を超高真空下に置くことが必要である点で実験が難しいが、硬X線ではその必要がなく簡便である、[2]試料への強磁場、高圧などの印加が容易であり、多彩な試料環境下で測定が可能である。SPring-8の共同利用研究採択課題「希土類元素L吸収端における四重極遷移XMCD理論の実験的検証」でESMの予備調査を行い、続いて課題「XMCDによる元素選択的磁気測定を用いた希土類合金のNon-Collinear磁気構造解析」において、DyCo_5合金におけるDy, CoのESM実験を遂行した。本結果は硬X線ESMの性質を細かく調べた結果であり、論文を準備中である。論文に先だって学会発表を行ったところ、Spring-8における注目すべき研究成果トピックスとして「SPring-8 Research Frontiers 2001/2002」に原稿執筆依頼を受けている。

In this project, we have performed several experimental studies on the spin, S=1 quasi-one-dimensional(Q1D) Heisenberg antiferromagnet Ni(C_5H_<14>N_2)_2N_3(PF_6)(abbreviated NDMAP) for which a field induced magnetic long range ordering (LRO)has been discovered by the present investigator and co-workers. From the temparature and magnetic field dependence of the magnetization, we got information on the spin arrangement in the ordered phase. Namely, at low temperature and high magnetic fields, spins are confined in the c plane and directed perpendicular to the external field. From electron spin resonance(ESR)measurements on NDMAP, we observed two kinds of signals at low temperature and high magnetic field, one of which corresponds to an antiferromagnetic resonance and the other to a one-dimensional excitation. This finding Provides a new knowledge towards the understanding of magnetic excitation in an S=1 Q1D antiferromagnet. We have also measured neutron scattering on deuterated single crystals of NDMAP and found a Bragg peak at(0, 1/2, 1/2)point associated with the long range magnetic ordering at high field and low temperature, thus confirming that the field unduced LRO really exists. In collaboration with theoretical physicists, we have analyzed the magnetic field versus temperature phase diagram of NDMAP.We calculated the staggered susceptibility of S=1 one dimensional system with a single ion snisotropy taking into account the effects of the inter-chain couplings as the form of a mean-field. The theoretical result well reproduces the experimental phase diagram obtained by us. We have measured the magnetic excitations from the ladder part of La_6Ca_8Cu_<24>O_<41> using a pulsed neutron source. We were successful in observing a full dispersion curve for the low energy excitation in the ladder. From the analysis of the data, we found that a four spin interaction with about 10% of the dominant interactions(leg and ladder) is necessary to get a reasonable result. In addition to these, we have studied several quantum magnets and obtained new results, details of which are reported in the booklet.
