项目摘要
This study aimed to search for materials with giant anomalous Nernst effect at room temperature with the hypothesis that the effect was brought by the inverse spin-Hall effect of spin current generated by the temperature difference. We focused on half-metallic Heusler alloys with high spin polarization and the L10-type ordered alloys such as FePt with high magnetic anisotropy. The anomalous Nernst effect and the spin-Seebeck effect of these materials were systematically measured, and the relation between the two effects was investigated, which leads to the development of materials with giant anomalous Nernst effect at room temperature.
本研究的目的是寻找在室温下具有巨反常能斯特效应的材料,并假设这种效应是由温差产生的自旋电流的逆自旋霍尔效应引起的。我们重点研究了具有高自旋极化的半金属Heusler合金和具有高磁各向异性的L10型有序合金,如FePt。系统地测量了这些材料的反常能斯特效应和自旋塞贝克效应,并研究了这两种效应之间的关系,从而发展了室温下具有巨反常能斯特效应的材料。
