本文简要介绍了自旋霍尔效应，即外加电场诱导横向自旋电流。30多年来人们已经认识到，这种效应是由于存在自旋轨道耦合的杂质而发生的。同时，最近有人提出，这一效应也有一个内在的贡献。我们解释了这种内在的自旋霍尔效应的机制。我们还讨论了最近的自旋霍尔效应的实验观察。
AbstractA brief review is given on a spin Hall effect, where an external electric field induces a transverse spin current. It has been recognized over 30 years that such effect occurs due to impurities in the presence of spin-orbit coupling. Meanwhile, it was proposed recently that there is also an intrinsic contribution for this effect. We explain the mechanism for this intrinsic spin Hall effect. We also discuss recent experimental observations of the spin Hall effect.
