    We investigate the electronic band structure and Fermi surfaces (FSs) of Cr2AlC single crystals with angleresolved photoemission spectroscopy. We evidence hole bands centered around the M points and electron bands centered around the Gamma point in reciprocal space. Electron and hole bands exhibit an open, tubular structure along the c axis, confirming the quasi-two-dimensional character of this highly anisotropic, nanolamellar compound. Dependence of the photoionization cross sections on beam light polarization and orientation allows us to assess the orbital character of each observed band locally. Despite some differences, density functional theory calculations show a good agreement with experiment.

    Herein we show that Mo4Ce4Al7C3, a recently discovered nanolamellar compound displaying mixed valence, combines Kondo lattice behavior with ferromagnetism. A sizeable magnetization is carried by 3p states of Al as evidenced by a strong x-ray magnetic circular dichroism signal at the K edge of aluminum, whereas no detectable signal was observed at the K edge of carbon and L2,3 edges of molybdenum. These results point out that the ferromagnetic behavior originates in the Ce atoms with 4f1 electronic configuration lying within the Al planes. The evolution with pressure of the mixed valence of Ce atoms in the Mo-C planes determined via Ce L3 x-ray-absorption spectra along with the magnetoresistance measurements across the ferromagnetic transition unambiguously reveal a Kondo behavior. Angle-resolved photoemission spectroscopy and density functional theory confirm a certain degree of Ce 4f electron delocalization. More generally, conduction electrons are not restricted to lie in the MoC planes but are also delocalized in the Al planes.

    An in-depth study of the Fermi surface and electronic structure of the ternary nanolamellar carbide Ti3SiC2 is reported. The outputs of angle-resolved photoemission spectroscopy (ARPES) measured on single crystals and density functional theory calculations are systematically compared. The band structure is found to be dominated by Ti d orbitals near the Fermi level. Band inversions near K points are responsible for the intricate shape of the Ti3SiC2 pockets. Previous theory found that those pockets were giving opposite contributions leading to zero thermoelectric power in polycrystalline samples. Here we directly visualize them by ARPES, describe their precise shape, and examine the way they should behave regarding thermoelectric power. The presence of linear band crossings and the effect of spin-orbit coupling on the near Fermi level electronic structure are discussed, as well as potential consequences for magnetotransport and spin Hall effect.

  9. Controlled growth of boron-doped epitaxial graphene by thermal decomposition of a B4C thin film

    We show that boron-doped epitaxial graphene can be successfully grown by thermal decomposition of a boron carbide thin film, which can also be epitaxially grown on a silicon carbide substrate. The interfaces of B4C on SiC and graphene on B4C had a fixed orientation relation, having a local stable structure with no dangling bonds. The first carbon layer on B4C acts as a buffer layer, and the overlaying carbon layers are graphene. Graphene on B4C was highly boron doped, and the hole concentration could be controlled over a wide range of 2 1013 to 2 1015 cm-2. Highly boron-doped graphene exhibited a spin-glass behavior, which suggests the presence of local antiferromagnetic ordering in the spin-frustration system. Thermal decomposition of carbides holds the promise of being a technique to obtain a new class of wafer-scale functional epitaxial graphene for various applications.

    For understanding of carrier behavior in semiconductors, it is important to measure the carrier relaxation time. In the present study, the relaxation times of inter-valley transition from the valley to the X valley in GaP were evaluated by near-band-gap photoemission spectroscopy of electrons emitted from a surface with a negative electron affinity state. In the energy distribution curves, two peaks, which originate from the electron population accumulated in the valley and the X valley, were observed. From the temperature dependence of the energy of these two peaks, we could successfully evaluate the temperature dependence of the energies of the valley and the X valley. Furthermore, the relaxation times of the inter-valley transition from the valley to the X valley were estimated from the ratio of the electron concentration of the valley and the X valley. The values of the relaxation time are good agreement with the previous studies. These results indicate that the near-band-gap photoemission spectroscopy can directly investigate conduction electrons and also evaluate the carrier dynamics in semiconductor. (C) 2017 Author(s).

    This study has been aimed at the realization of angle-resolved photoelectron spectroscopy (ARPES) and absorption spectroscopy (XAS) measurements by utilizing linear/circularly polarized microfocus VUVSX synchrotron light at AichiSR and the exploration of novel topological-materials. For the former, the polarization-dependent VUVSX synchrotron radiation imaging spectroscopy system in Aichi SR is limited for fixed photon energy, owing to the beam instability as remaining issue. For the latter, we found the existence of spin-polarization tangential to the Fermi surface with Rashba-type spin-splitting on the layered MAX phase compound V2AlC and the existence of unique helicoid electronic states on the cubic chiral compound NiSbS.

    We have developed a new spectroscopic research technique “VUVSX-micro-imaging spectroscopy” utilizing micro-focus and elemental selectivity of the VUVSX synchrotron radiation source. We applied the technique to Sm1-xYxS in which existence of the micrometer scale surface domain has been expected and to quasi-one dimensional micrometer size crystal of Ba3Co2O6(CO3)0.7. As results, we have found that the coexistence of localized and itinerant Sm 4f electrons in black-metallic Sm1-xYxS and the narrow band dispersion of t2g AB orbital below the Fermi level originating from the effect of CoO6-CO3 inter-chain interactions in Ba3Co2O6(CO3)0.7.

    反強磁性体と磁気スキルミオンはメモリー素子・ロジック素子開発にイノベーションをも たらす次世代材料として注目を集めている。ノンコリニア(非共線)磁気構造は,反強磁性 体や磁気スキルミオンで現れる構造であり,それらの磁性体の物性・機能発現に対して本質 的に重要な役割を果たしている。
    本研究では,複金属窒化物のノンコリニア反強磁性体と磁気スキルミオン における巨大磁気伝導物性を開拓するとともに,それらの融合系としての「反強磁性スキル ミオン」の創成とその応用を目的とする。本研究の成果は,革新的なスピンデバイス開発の 基礎となる「反強磁性スキルミオニクス」の創製に繋がるものである。
    本研究では,ノンコリニアな磁気構造を有する反強磁性体と磁気スキルミオンにおける新奇な巨大磁気伝導物性・機能の開拓,およびそれら2つの物質の特徴を合わせ持つ「反強磁性スキルミオン」の創成、を目的としている。
    ノンコリニア反強磁性体については、逆ペロブスカイト窒化物反強磁性体Mn3GaNを用いて電流駆動による反強磁性スピンの効率的制御に関する研究を進めた。スピン流生成源であるPtやTaとの積層構造において、Mn3GaNの反強磁性スピンの磁化反転を異常ホール信号により検出する系統的な実験から、反強磁性スピンの磁化反転機構がスピン軌道トルク効果によるものであり、室温、無磁場、106/Acm2の低電流密度という応用上重要な要件が満たされていることを実証した。
    磁気スキルミオンについては、反転対称性の破れた窒化物強磁性体Fe2-yXyMo3N系薄膜 (X = Ni, Pd, Pt)に対する探索的な検討を行い、X = Pdにおける特定の組成領域において、温度に依存して2種類のスキルミオン相が発現し、室温以上まで強磁性スキルミオンが発現すること、また、これらのスキルミオン相は、温度によらず60 nmの微小サイズを有することが分かった。これらの結果は、スキルミオンの磁気メモリーなどへのデバイス応用上重要な室温動作と微小サイズが同時に実現できることを意味するものであり、これらの材料系の応用上の有用性を明らかにすることができた。
    本研究の第一の検討課題である、ノンコリニアな磁気構造を有する反強磁性体と磁気スキルミオンにおける新奇な巨大磁気伝導物性・機能の開拓については、電流駆動による反強磁性スピンの効率的制御、および強磁性スキルミオンにおける室温動作と微小サイズ化が達成されていることから、当初の予定通り研究は進展していると考えている。これらの2つの研究成果については、既に関連論文が出版されている。従って、第一の検討課題の達成度は80%程度であり、さらに、これらの研究の完成度を高めることにより、第2の検討課題である反強磁性体スキルミオンの実現を目指すこととする。
    本研究の最重要課題は、「反強磁性スキルミオン」の実現である。「反強磁性スキルミオン」は,反強磁性体としての超高速性,外乱に対する安定性とともに,スキルミオンとしてのトポロジカルに保護された粒子性を併せ持つ夢の物質であり,その応用が大いに期待されているが,未だに理論予測に留まっている。これまでの本研究で得られた、複金属窒化物におけるノンコリニア反強磁性体および強磁性スキルミオンに関する知見を総合することにより、複金属窒化物をベースのエピタキシャル薄膜における「反強磁性スキルミオン」の実現する。予備的な検討として、強磁性体Fe2-yXyMo3N系薄膜材料におけるFeサイトを全てCoに置換したCo2Mo3N系薄膜では反強磁性交換相互作用が支配的になることを磁気測定から明らかにしている。そこで、これら系に対して、スピンー軌道作用が強い Pd等の重金属を部分置換し、スキルミオン生成の要因となるジャロシンスキーー守谷相互作用を制御することにより、室温以上の磁気転移温度を有する「反強磁性スキルミオン」を探求する。また、反強磁性スキルミオンについては,強磁性スキルミオンと異なりその電気的検出法が確立されていないため,その新しい検出法の開拓に取り組む。

    We have developed a new spectroscopic research technique “micrometer function imaging” for “Fermiology” of strongly correlated electron systems, at the micro-focus vacuum-ultraviolet synchrotron angle-resolved photoemission spectroscopy beamline BL7U(@UVSOR-II). When we applied the technique to the quasi-one-dimensional organic conductor (TMTSF)2PF6, where the radiation damage and the surface domains disturb the intrinsic “Fermiology” research, we have successfully observed the Luttinger surface formed by the quasi-particle dispersion, which is suggestive of the strong electron-phonon interactions.
