论文摘要
磁性拓扑绝缘子（MTIS）中磁性和拓扑结合导致了过去十年来时间逆转对称性拓扑量子物理学的前所未有的进步。与均匀膜相比，MTI异质结构为操纵自旋轨道耦合和自旋特性提供了更好的框架。在这篇综述中，我们总结了与基于（BI，SB）2（TE，SE）3基于3的混合系统的物理订单相关的基本机制。此外，我们还提供了一般策略的评估，以通过不同的结构工程方法和有效的界面相互作用来增强磁耦合和旋转轨道扭矩强度。最后，我们提供了基于MTI异质结构的SpinTronics应用程序的前景，特别是考虑到它们实现室温操作的可行性。
The combination of magnetism and topology in magnetic topological insulators (MTIs) has led to unprecedented advancements of time reversal symmetry-breaking topological quantum physics in the past decade. Compared with the uniform films, the MTI heterostructures provide a better framework to manipulate the spin-orbit coupling and spin properties. In this review, we summarize the fundamental mechanisms related to the physical orders host in (Bi,Sb)2(Te,Se)3-based hybrid systems. Besides, we provide an assessment on the general strategies to enhance the magnetic coupling and spin-orbit torque strength through different structural engineering approaches and effective interfacial interactions. Finally, we offer an outlook of MTI heterostructures-based spintronics applications, particularly in view of their feasibility to achieve room-temperature operation.
