本视角讨论了凝聚态物质中磁性和拓扑之间的相互作用。拓扑电子材料，例如拓扑绝缘体，其电子能带结构的拓扑不同于普通材料，可以产生鲁棒的、非常规的拓扑态，这可能会带来电子学的革命性发展。本视角总结了拓扑绝缘体在各种电子应用（包括自旋电子学和磁电子学）中的发展。我们使用拓扑绝缘体对自旋电子学中的几个重要现象进行分组和分析，包括自旋轨道扭矩、磁邻近效应、反铁磁性和拓扑之间的相互作用以及拓扑自旋纹理的形成。我们还概述了磁电子学的最新进展，例如轴子绝缘体和使用不同拓扑绝缘体观察到的拓扑磁电效应。
This Perspective discusses the interplay between magnetism and topology in condensed matter.Topological electronic materials, such as topological insulators, are distinct from trivial materials in the topology of their electronic band structures that lead to robust, unconventional topological states, which could bring revolutionary developments in electronics. This Perspective summarizes developments of topological insulators in various electronic applications including spintronics and magnetoelectronics. We group and analyse several important phenomena in spintronics using topological insulators, including spin-orbit torque, the magnetic proximity effect, interplay between antiferromagnetism and topology, and the formation of topological spin textures. We also outline recent developments in magnetoelectronics such as the axion insulator and the topological magnetoelectric effect observed using different topological insulators.
