无序Rashba自旋轨道系统中自旋动力学驱动的电荷流

Charge current driven by spin dynamics in disordered Rashba spin-orbit system

Jun-ichiro Ohe, Akihito Takeuchi, Gen Tatara

摘要:

从理论上研究了存在Rashba自旋轨道相互作用时自旋动力学对电荷流的抽运。考虑无序电子,对交换耦合和自旋轨道相互作用作微扰处理。结果表明,自旋动力学引起的主导电流被解释为自旋电流通过逆自旋霍尔效应转换的结果。我们还发现,电流有一个额外的组成部分,从一个虚构的保守领域。结果适用于移动畴壁的情况。

英文摘要:

Pumping of charge current by spin dynamics in the presence of the Rashba spin-orbit interaction is theoretically studied. Considering disordered electron, the exchange coupling and spin-orbit interactions are treated perturbatively. It is found that dominant current induced by the spin dynamics is interpreted as a consequence of the conversion from spin current via the inverse spin Hall effect. We also found that the current has an additional component from a fictitious conservative field. Results are applied to the case of moving domain wall.
