论文摘要
在具有自旋轨道耦合的金属系统中，纵向电荷电流可能会产生横向纯自旋电流。反之亦然，注射的纯自旋电流可能导致横向电荷电流。这种直接和反自旋霍尔效应具有相同的显微镜来源：内在的频带/设备结构特性，诸如杂质或两者组合之类的外部因素。它们允许全电动操作电子自由度的自由度，即。没有磁性元素，它们的横向性质会使它们潜在地耗散。习惯上以复数形式谈论旋转厅效应，这是指降低对称性的旋转轨道耦合系统的一组相关现象。
In metallic systems with spin-orbit coupling a longitudinal charge current may generate a transverse pure spin current; vice-versa an injected pure spin current may result in a transverse charge current. Such direct and inverse spin Hall effects share the same microscopic origin: intrinsic band/device structure properties, external factors such as impurities, or a combination of both. They allow all-electrical manipulation of the electronic spin degrees of freedom,i.e. without magnetic elements, and their transverse nature makes them potentially dissipationless. It is customary to talk of spin Hall effects in plural form, referring to a group of related phenomena typical of spin-orbit coupled systems of lowered symmetry.
