  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
(>200meV), 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.
