  1. トポロジカル磁性体のマグノンドラッグ効果を用いたスピン流熱電効果

    排熱や温度差を電気エネルギーに変換できる熱電効果において、従来のバルク電子系の枠組みを超えたエネルギー変換機構が求められている。特に、磁性材料を用いた熱電変換では、マグノン・電子相互作用により、大きな熱電効果を生み出すことができる。
    本研究は、従来の一様磁化を用いた磁性熱電効果を発展させ、非一様磁化構造の磁化ダイナミクスから誘起されるマグノンドラッグ効果に着目した巨大磁性熱電効果の理論的研究を行う。特に、トポロジカルに保護されたねじれた磁化構造中に誘起されるスピン波や、磁気超格子における指向性スピン波を利用した新しい磁性熱電効果の提案を行う。

    これまで主に一体問題のレベルで議論されてきたスピントロニクスの諸現象を、多体相互作用の観点から見直し、その効果を増強する指針などを探る。具体的には、磁化構造に起因するホール効果(トポロジカル・ホール効果)や、各種スピン輸送における種々のドラッグ効果(相互作用し合う素励起の流れが互いに引きずり合う効果)を調べる。後者についてはとくに、スピントロニクスのパラダイムに従って素励起間の角運動量転換の観点からドラッグ効果を調べ、増強のための知見を深める。
    ●傾角反強磁性体におけるトポロジカルホール効果
    有限の立体角を張る磁化構造により引き起こされるホール効果(トポロジカルホール効果)を、傾角反強磁性体に対して解析的に調べた。運動エネルギーに比べて反強磁性交換相互作用が強い領域では、ホール抵抗が電子の有効質量の2乗に比例することを見出した。これは、マンガン酸化物で観測されている巨大なホール効果の理解に重要となる可能性がある。また、理論的に興味深いこととして、有効磁場(有効ベクトルポテンシャル)の表式が、反強磁性体の磁化ダイナミクスを記述するラグランジアンの運動項と、空間・時間成分の対応があることを見出した。結果は Phys. Rev. B 誌に掲載された。
    <BR>
    ●トポロジカルネルンスト効果に対するマグノンドラッグ効果
    トポロジカルホール効果の熱電版であるトポロジカルネルンスト効果に着目してマグノンドラッグ効果(マグノンの流れに引きずられて電子の流れが生じる効果)を調べた。具体的には、磁化構造存在下で温度勾配によって誘起される横電流を計算した。横方向の流れが生じる過程(M:マグノンのトポロジカルホール効果、E:電子のトポロジカルホール効果)とマグノン流が電子流を誘起する過程(S:スピン移行効果、P:運動量移行効果)との4通りの組み合わせのうち、(M,S)を除く他の3つの過程に対応する表式を解析的に得た。(M,S)が存在しない物理的理由として、マグノンドラッグにおけるスピン移行効果は準平衡過程であるためであると議論した。東邦大学の大江研究室で行われたシミュレーションの結果を、今回得られた表式で解析することにより、上記諸過程のうち(M,P)の組み合わせが支配的であることを見出した。シミュレーションとその解析結果については Appl. Phys. Lett. 誌に掲載された。

    The purpose of this research is to create conductors by irradiating light to oxide insulators, to precisely measure their transport parameters, and to clarify the transport properties and microscopic mechanism of the photo-doped carrier.
    Various insulators such as ZnS, ZnO, SrTiO3, CuO, La2CuO4, CuFeS2 were irradiated with light from visible to ultraviolet region. Then we quantitatively measured the photoconductivity, the photo-Hall coefficient, and the photo-Seebeck coefficient, and have clarified the transport characteristics of the photo-doped carrier. In particular, we have revealed that the thermopower is screened by quantum paraelectricity in SrTiO3. We have also found that thin films, single crystals and polycrystaline samples of ZnO show nearly the same saturated photo-Seebeck coefficient.
