这是陀螺半导体纳米结构中电流引起的自旋极化的概述。作为对充电电流的响应的这种自旋极化可以被分类为自旋电偶效应的逆，并且有时被称为磁电效应或埃德尔斯坦（Rashba-Edelstein）效应。除了回顾事件的实验状况之外，我们还根据自旋相关弛豫过程的唯象模型以及基于准经典玻尔兹曼方程的替代理论方法对这两种效应进行了详细的理论描述。
This is an overview of current-induced spin polarization in gyrotropic semiconductor nanostructures. Such a spin polarization as response to a charge current may be classified as the inverse of the spin-galvanic effect, and sometimes is called as magneto-electrical effect or Edelstein (Rashba-Edelstein) effect. Apart from reviewing the experimental status of affairs, we have provided a detailed theoretical description of both effects in terms of a phenomenological model of spin-dependent relaxation processes, and an alternative theoretical approach based on the quasi-classical Boltzmann equation.
