Abstract

A system of coupled kinetic equations for the electron density and spin density distribution functions has been obtained based on the quantum kinetic equation. The collision integrals in the kinetic equations are written for an arbitrary scattering potential, taking into account the spin-orbit interaction of conduction electrons with scattering defects. As applied to the spin system of conduction electrons, the idea of a “reduced” description of transport phenomena is developed. The description of the system in terms of distribution functions depending on the quasi-momentum of electrons reduces to a description in terms of macroscopic mean quantities: electron density, spin density, electron flux, and spin current.

金属中的电子自旋电流和自旋相关的电磁现象

摘要

基于量子动力学方程，获得了一个用于电子密度和自旋密度分布函数的耦合动力学方程组。考虑到导电电子与散射缺陷的自旋轨道相互作用，在动力学方程中的碰撞积分是针对任意散射势编写的。当应用于传导电子的自旋系统时，提出了一种“减少”的输运现象描述的思想。关于根据电子的准动量的分布函数的系统描述简化为关于宏观平均量的描述：电子密度，自旋密度，电子通量和自旋电流。
