论文摘要
物质的拓扑状态具有宽大的电子结构，该结构由拓扑不变性和边缘/表面状态分类，这是由于宽大的对应关系。拓扑材料在开发无耗散的旋转型，信息存储和量子计算方面具有巨大的潜力，尤其是与本质上或外部的磁顺序结合在一起。在这里，我们回顾了探索固有磁性拓扑材料的最新进展，包括但不限于磁性拓扑绝缘子，磁性拓扑金属和磁性Weyl半含量。我们特别注意它们的特征频带特征，例如拓扑表面状态的间隙，磁化强度（散装或表面），Weyl节点/线和Fermi Arc引起的间隙Dirac锥，以及由此类频段特征引起的外来传输响应。我们通过将其他订单纳入固有的磁性拓扑材料中，简要介绍了对新物理学或效果的实验探索的简短设想。
Topological states of matter possess bulk electronic structures categorized by topological invariants and edge/surface states due to the bulk-boundary correspondence. Topological materials hold great potential in the development of dissipationless spintronics, information storage, and quantum computation, particularly if combined with magnetic order intrinsically or extrinsically. Here, we review the recent progress in the exploration of intrinsic magnetic topological materials, including but not limited to magnetic topological insulators, magnetic topological metals, and magnetic Weyl semimetals. We pay special attention to their characteristic band features such as the gap of topological surface state, gapped Dirac cone induced by magnetization (either bulk or surface), Weyl nodal point/line, and Fermi arc, as well as the exotic transport responses resulting from such band features. We conclude with a brief envision for experimental explorations of new physics or effects by incorporating other orders in intrinsic magnetic topological materials.
