Outline of Final Research Achievements

The steering committee led collaborative research between 5 research groups. We demonstrated that the spin conversion is a universal principle based on the conservation law of angular momentum, that extends to solid-liquid, solid-gas interfaces as well as solid-solid interfaces. We also showed that it is a ubiquitous phenomenon. This collaborative research project has been highly evaluated and resulted in 87 awards, including Minister of Education, Culture, Sports, Science and Technology Commendation, i.e., 3 Young Scientists and 4 Science and Technology Awards. The member principal researchers have given 15 plenary talks, and 501 invited talks at various international conferences on spintronics. Besides, we organized three international meetings to raise the international recognition of the research field for forming a base for developing an international spin conversion collaborative research. These achievements resulted in the initiative for human resource and research development.

Academic Significance and Societal Importance of the Research Achievements

本領域研究の成果がもたらした意義は次のとおりである。スピン変換関連研究は、もともと個々の研究者が独自に研究を遂行していた理学と工学の新興学際分野であったが、本領域発足を契機にこの分野に関わる研究者が集まり、情報交換しながら研究を進めたことで、本分野にパラダイムシフトをもたらし、次世代の諸学問の基本概念の構築に導いた。さらに新概念創出の起爆剤としてスピン変換(spin conversion)という言葉が国際的にも認知され、通常の国内外の会議でも使われる科学用語になり、融合研究の潮流を作ることができた。
