Outline of Final Research Achievements

In this study, we pursue the theory of spinmotive force, the principle of magnetic-electric energy conversion via electron spin degrees of freedom in solids, and propose a method of increasing its power to pave the way for innovative nanoelectronics applications. In particular, we have demonstrated and established elemental technologies for enhancing the output power through joint research with related experimental groups, focusing on antiferromagnets as magnetic materials, magnetic skyrmions as magnetic nanostructures, and spin-wave excitation as magnetization dynamics. In addition, we have conducted international joint research on the generation mechanism of spinmotive force by magnetic nanoparticles, which has been unsolved for more than 10 years.

Academic Significance and Societal Importance of the Research Achievements

スピン起電力は、スピン流(電子のスピン角運動量の流れ)の生成と制御を通じて次世代エレクトロニクスの創出をはかるスピントロニクス分野の新概念である。同分野では、巨大磁気抵抗効果やスピン移行トルクといった新原理の発見に基づく新しい磁気メモリなど、既存素子の高性能化を主眼とした応用とそれに資する基礎研究が追及されており、これらは究極的な「省エネルギー」技術として広く認知されている。これに加えスピン起電力は、磁気・電気の変換原理を提供し、ナノ構造磁性体を用いたエネルギーハーベスティングなど「創エネルギー」の基本概念を導入するものであり、当該分野の今後の発展に質的転換をもたらす可能性を有している。
