论文摘要

旋转Seebeck效应(SSE)是指磁性材料中温度梯度的产生旋转电流,可以通过金属接触中的反旋转厅效应进行电检测。自2008年发现SSE以来,已经对SSE进行了深入研究以阐明其起源。 SSE出现在各种磁性材料中,包括铁,铁和抗铁磁体,以及具有经典或量子自旋波动的Parmagnets。 SSE电压反映了磁铁的基本特性,例如基本激发,静态磁性,自旋相关和自旋传输。在本文中,我们回顾了各种系统中SSE的最新进展,尤其强调了它作为对固体中这些磁性特性的探测作用。我们还简要讨论了最近发现的核SSE。

The spin Seebeck effect (SSE) refers to the generation of a spin current as a result of a temperature gradient in a magnetic material, which can be detected electrically via the inverse spin Hall effect in a metallic contact. Since the discovery of SSE in 2008, intensive studies on SSE have been conducted to elucidate its origin. SSEs appear in a wide range of magnetic materials including ferro-, ferri-, and antiferro-magnets and also paramagnets with classical or quantum spin fluctuation. SSE voltage reflects fundamental properties of a magnet, such as elementary excitation, static magnetic order, spin correlation, and spin transport. In this article, we review recent progress on SSEs in various systems, with particular emphasis on its emerging role as a probe of these magnetic properties in solids. We also briefly discuss the recently-discovered nuclear SSE.
