拓扑绝缘体和拓扑半金属的研究一直处于凝聚态物理和材料科学的前沿。这两类材料的特征都是由体带结构的拓扑结构产生的强健的表面态，并显示出奇异的输运性质。当拓扑材料中存在磁性并破坏时间反转对称性时，可以产生更多奇异的量子现象，如量子反常霍尔效应、轴子绝缘体、大本征反常霍尔效应等。在这一研究更新中，我们简要地综述了磁性拓扑材料，包括本征磁性拓扑绝缘体和磁性Weyl半金属的最新研究进展。
The studies of topological insulators and topological semimetals have been at frontiers of condensed matter physics and material science. Both classes of materials are characterized by robust surface states created by the topology of the bulk band structures and exhibit exotic transport properties. When magnetism is present in topological materials and breaks the time-reversal symmetry, more exotic quantum phenomena can be generated, e.g. quantum anomalous Hall effect, axion insulator, large intrinsic anomalous Hall effect, etc. In this research update, we briefly summarize the recent research progresses in magnetic topological materials, including intrinsic magnetic topological insulators and magnetic Weyl semimetals.
