Outline of Final Research Achievements

We have theoretically investigated the stabilization mechanism and magneto-transport phenomena under a plethora of chiral magnetic textures in itinerant magnets. We have shown that the Bloch-type and/or Neel-type skyrmion crystals are stabilized by the interplay between the spin-orbit coupling and the spin-charge coupling in noncentrosymmetric itinerant magnets. We also found that various multiple-Q states are induced by the Fermi surface instability of itinerant electrons in centrosymmetric itinerant magnets. Furthermore, we have constructed an effective model to account for magnetic skyrmion crystals and magnetic bubble crystals discovered in experiments. We also have analyzed magneto-transport phenomena in these chiral magnetic orderings.

Academic Significance and Societal Importance of the Research Achievements

近年、トポロジカルに非自明な磁気構造を有するスキルミオン結晶に関する研究が急速に進展しつつある。本研究の主な成果は、従来は主に磁性絶縁体に対して行われてきた理論解析を、カイラルな金属磁性にまで拡張し、さらに金属系に特有の磁気相互作用を利用することにより、スキルミオン結晶の新しい安定化機構や磁気伝導特性を明らかにしたことである。さらには、現実物質で見出されたカイラルな磁気構造の微視的起源を説明する理論模型の構築に成功した。これにより、従来理論の枠組みでは説明できない多くのカイラル磁気構造を説明することができるようになり、さらなる特異な磁気構造をもつ物質探索への礎を築いた。
