Emergent Phenomena in Magnetic Two-Dimensional Materials and van der Waals Heterostructures

Abstract

Two-dimensional (2D) materials and their van der Waals (vdW) heterostructures provide powerful platforms for exploring fascinating physical phenomena and implementing intriguing applications. The recent discovery of 2D magnetic materials opens up many exciting topics in the research of 2D materials. 2D magnetic materials not only exhibit diverse properties on their own, which can be effectively controlled via external stimuli, but also can serve as a part of vdW heterostructures, creating a variety of unprecedented properties and functionalities. The field of 2D magnetism has grown rapidly in the past few years. In this review, we summarize the recent progress on the emergent phenomena in this active field. We review the well-established understanding of typical 2D magnetic materials and the vdW heterostructures and introduce the manipulations of their magnetic properties. In addition, we discuss the interplay between magnetism and topology in some recently discovered 2D materials. Moreover, we also address the valley relevant physics and the topological spin textures in 2D magnetic materials. Finally, we highlight some future interests in this promising field.
