Finding new two-dimensional (2D) materials with novel quantum properties is highly desirable for technological innovations. In this work, we studied a series of metal–organic frameworks (MOFs) with different metal cores and discovered various attractive properties, such as room-temperature magnetic ordering, strong perpendicular magnetic anisotropy, huge topological band gap (>200 meV), and excellent spin-filtering performance. As many MOFs have been successfully synthesized in experiments, our results suggest realistic new 2D functional materials for the design of spintronic nanodevices.

金属有机框架：可能的新型二维磁性和拓扑材料

寻找具有新颖量子特性的新型二维（2D）材料对于技术创新是非常必要的。在这项工作中，我们研究了具有不同金属核的一系列金属有机骨架（MOF），并发现了多种吸引人的特性，例如室温磁有序，强垂直磁各向异性，巨大的拓扑带隙（> 200 meV）和出色的自旋过滤性能。由于许多MOF已在实验中成功合成，因此我们的结果提出了用于自旋电子纳米器件设计的现实的新型2D功能材料。
