| Research Abstract |
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.
