Abstract

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 the SSE have been conducted to elucidate its origin. SSEs appear in a wide range of magnetic materials including ferro-, ferri-, and antiferromagnets 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 the 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. Expected final online publication date for the Annual Review of Condensed Matter Physics, Volume 14 is March 2023.

自旋塞贝克效应:固体中初等激发、自旋相关、输运、磁序和畴的敏感探针

自旋塞贝克效应（SSE）是指由于磁性材料中的温度梯度而产生的自旋电流，可以通过金属接触中的反向自旋霍尔效应进行电检测。自2008年发现SSE以来，人们对SSE进行了深入的研究，以阐明其起源。SSE出现在广泛的磁性材料中，包括铁磁体、铁磁体和反铁磁体，以及具有经典或量子自旋波动的顺磁体。SSE电压反映了磁体的基本特性，如基本激发、静态磁序、自旋相关和自旋输运。在这篇文章中，我们回顾了SSE在各种系统中的最新进展，特别强调了它作为固体中这些磁性性质的探针的新兴作用。我们还简要讨论了最近发现的核SSE。《凝聚态物理学年度评论》第14卷预计最终在线出版日期为2023年3月。请参阅http://www.annualreviews.org/page/journal/pubdates用于修订估算。
