旋转霍尔阻力

Spin Hall Drag

S. M. Badalyan, G. Vignale

摘要:

我们预测了电子双层膜中的一种新效应:{ \it自旋霍尔拖曳}。该效应在于通过沿另一层的电流在一层上产生自旋累积。它是由自旋-轨道相互作用和库仑相互作用的联合作用引起的。我们的理论分析,玻尔兹曼方程形式主义的基础上,确定两个主要贡献的自旋霍尔阻力:侧跳的贡献,这在低温下占主导地位,去作为$T^2$,和斜散射的贡献,这是成比例的$T^3$。诱导的自旋积累足够大,可以在旋光实验中检测到。

英文摘要:

We predict a new effect in electronic bilayers: the {\it Spin Hall Drag}. The effect consists in the generation of spin accumulation across one layer by an electric current along the other layer. It arises from the combined action of spin-orbit and Coulomb interactions. Our theoretical analysis, based on the Boltzmann equation formalism, identifies two main contributions to the spin Hall drag resistivity: the side-jump contribution, which dominates at low temperature, going as $T^2$, and the skew-scattering contribution, which is proportional to $T^3$. The induced spin accumulation is large enough to be detected in optical rotation experiments.
