Two-dimensional (2D) magnetism and nontrivial band topology are both areas of research that are currently receiving significant attention in the study of 2D materials. Recently, a novel class of materials has emerged, known as 2D magnetic topological materials, which elegantly combine 2D magnetism and nontrivial topology. This field has garnered increasing interest, especially due to the emergence of several novel magnetic topological states that have been generalized into the 2D scale. These states include antiferromagnetic topological insulators/semimetals, second-order topological insulators, and topological half-metals. Despite the rapid advancements in this emerging research field in recent years, there have been few comprehensive summaries of the state-of-the-art progress. Therefore, this review aims to provide a thorough analysis of current progress on 2D magnetic topological materials. We cover various 2D magnetic topological insulators, a range of 2D magnetic topological semimetals, and the novel 2D topological half-metals, systematically analyzing the basic topological theory, the course of development, the material realization, and potential applications. Finally, we discuss the challenges and prospects for 2D magnetic topological materials, highlighting the potential for future breakthroughs in this exciting field.
二维（2D）磁性和非平凡能带拓扑都是目前二维材料研究中备受关注的领域。最近，一类新型材料出现了，即二维磁性拓扑材料，它巧妙地结合了二维磁性和非平凡拓扑。这个领域已经引起了越来越多的关注，特别是由于出现了几种新型磁性拓扑态，这些态已被推广到二维尺度。这些态包括反铁磁拓扑绝缘体/半金属、二阶拓扑绝缘体和拓扑半金属。尽管近年来这个新兴研究领域取得了快速进展，但对其最新进展的全面总结却很少。因此，本综述旨在对二维磁性拓扑材料的当前进展进行全面分析。我们涵盖了各种二维磁性拓扑绝缘体、一系列二维磁性拓扑半金属以及新型二维拓扑半金属，系统地分析了基本拓扑理论、发展历程、材料实现以及潜在应用。最后，我们讨论了二维磁性拓扑材料面临的挑战和前景，突出了这个令人兴奋的领域未来取得突破的潜力。
