Outline of Research at the Start

磁性体の集団的磁気秩序の電気的制御はスピントロニクスの中心的課題である。本研究ではこの分野で未開拓の磁気秩序-ノンコリニア磁気構造-に着目し、磁気秩序の電気的制御に新展開をもたらす。これまでに多くの研究がなされているコリニア系における現象の理解を発展させ、そこで確立した地図と道具を携え“ノンコリニアスピントロニクス”に挑む。ノンコリニア磁気構造を介して発現する数々の新奇物理現象を観測し、スピントロニクス素子としての利用方法を実験で明らかにする。これらは超高速不揮発性磁気メモリや脳型情報処理に向けた新たな基盤となる。

Outline of Final Research Achievements

Electrical control of collective magnetic ordering in magnetic systems is a central focus in the field of spintronics. In the past years, collinear magnetic orders such as magnetization in ferromagnets and Neel vectors in antiferromagnets have been investigated as the object for electrical control, and magnetic fields, spin-transfer torques, and spin-orbit torques have been used as driving forces for them. In this project, we focus on non-collinear magnetic structures in both the magnetic order to be controlled and the source of the driving force for the magnetic order control. We have obtained results on the control of magnetic order using spin currents generated by the Berry curvature (fictitious magnetic field) of chiral spin structures and on the electrical control of chiral spin structures in noncollinear antiiferromagnets.

Academic Significance and Societal Importance of the Research Achievements

磁性体の磁気秩序の電気的制御は、伝導電子スピンとローカルな磁気構造の相互作用によってもたらされる。これまで「磁場」、「スピン移行トルク」、「スピン軌道トルク」が磁気秩序の制御の駆動力の生成源、「磁化」、「ネールベクトル」が制御の対象となる磁気秩序として扱われていたのに対して、本研究により「仮想磁場」、「カイラルスピン構造」がこの枠組みに加わった。これはスピントロニクスの学理を一段階発展させる学術的に意義のある成果である。加えて磁気秩序の電気的制御は不揮発性磁気メモリで利用されており、また超高性能・超低消費電力新原理コンピュータの実現への扉を開くものであり、この点で高い社会的意義も有している。
