Outline of Final Research Achievements

Magnetization is a macroscopic physical quantity, and its spatiotemporal change in phase is a collective excitation called a spin wave. By driving the spin wave with an alternating magnetic field or a temperature gradient, a spin current, which is a magnetic flow, is generated. In this study, we focused on the electron correlation effect on spin current generation and spin current conversion. It is found that the coherence of spin wave excitation is lost due to electron correlation. By the spin Hall effect, mutual conversion between spin and charge current is induced. We find that the electron correlation change its sign in Ir doped Cu. We also show that the thermal Hall effect can occur due to the local structural change of the spin cluster accompanied by the electron correlation.

Academic Significance and Societal Importance of the Research Achievements

現在、世界がしのぎを削る研究の的となっているのが,スピン流の物理である。スピントロニクスの研究は応用面だけでなく、基礎物理学にも豊かな色彩を放ち始めている。初期の磁気抵抗効果を中心とした研究から、現在は電流やスピン流を使う試みは新たな段階に入っている。スピン流を基軸にした熱電発電の原理(スピンゼーベック効果)はその典型である。スピンゼーベック効果では、スピン流の生成・注入・変換により起こる。本研究成果は、スピン流に対する電子相関の効果を示したものであり、新たな段階に入ったスピントロニクス研究へ貢献するものと位置付けられる。
