スピン流によらないスピンホール（ネルンスト）効果の定式化

Abstract

<p>Spin Hall (Nernst) effect has been recognized as a response of “spin current” to an electric field (a temperature gradient). However, “spin current” is ill defined in the presence of a spin-orbit coupling, which is the origin of these phenomena. Here, we propose a new formalism focusing on the spin accumulation at the boundaries. We consider the responses of spin to the gradients of the electric field and temperature gradient, and prove the generalized Mott relation between them and Onsager’s reciprocity relation. This formalism provides a new charge (heat)-spin conversion efficiency that can be evaluated by first-principles calculations.</p>
