Two-Dimensional Magnetic Nanostructures

Two-dimensional (2D) nanostructures with robust room-temperature ferromagnetism or ferrimagnetism have attracted significant attention because of their potential applications in fundamental research, integrated circuits, and next-generation spintronic devices. Magnetic order in 2D nanostructures can be divided into intrinsic and defect-induced magnetism. In this review, we highlight recent progress on the synthesis and magnetic properties of intrinsic 2D magnetic van der Waals nanostructures, such as VS2, CrI3, and 2D metal-organic frameworks. In addition, defect-induced magnetism in several systems such as graphene, MoS2 nanosheets, and Ni3N nanosheets are briefly introduced. Finally, we discuss future prospects for this booming research area.
