摘要

拓扑绝缘体(TI)体态在TI/铁磁体(FM)界面记录的巨大自旋力矩中的作用尚不清楚。在这里，我们研究了由于TI体态聚焦于磁化TI而引起的自旋力矩。我们发现在非均匀磁化条件下存在一种新的自旋传递转矩，它在我们的理想中很小

Current-induced spin polarizations in the bulk of topological insulators with inhomogeneous magnetic textures

The role of topological insulator (TI) bulk states in the the enormous spin torques recorded at TI/ferromagnet (FM) interfaces is poorly understood. Here we study spin torques due to TI bulk states focusing on magnetized TIs. We find that there is a novel spin transfer torque on an inhomogeneous magnetization, it is small in our idealized
