Outline of Research at the Start

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。

Outline of Final Research Achievements

(1) Microscopic calculations have been performed on the topological Hall effect, topological spin Hall effect, and spin-motive forces for collinear and/or canted antiferromagnets, where the Berry phase picture (which assumes adiabatic process) breaks down and non-adiabatic processes become important. The emergent electromagnetic (or spin-motive) field and emergent spin vector potential in antiferromagnets have been identified. (2) Microscopic calculations of spin-transfer torque in antiferromagnets have been performed. (3) Magnon-drag processes in the presence of topological spin structure have been studied. (4) Microscopic theory of Dzyaloshinskii-Moriya interaction mediated by band electrons with strong spin-orbit interaction have been developed. (5) Effects of spin-orbit interaction on mechanical spin-current generation have been investigated microscopically starting from a multi-orbital tight-binding model.

Academic Significance and Societal Importance of the Research Achievements

スピントロニクスの基礎理論を、強磁性体から反強磁性体へ、電気的摂動から力学的摂動へ、一様磁化下のマグノンドラッグから磁化構造下のマグノンドラッグへ、といった方向へ進展させた。また、ジャロシンスキー・守谷相互作用の微視的理論を構築した。
