2D Magnetic Heterostructures and Emergent Spintronic Devices

The discovery of 2D intrinsic magnetic materials with ultrathin structures and smooth surfaces has enabled the investigation of fundamental magnetism physics and creation of spintronic devices. By vertically stacking 2D magnetic materials with other magnetic or nonmagnetic materials, various magnetic heterostructures and spintronic devices can be developed. Recent progress in emergent 2D magnetic heterostructures and spintronic devices is reviewed. First, various typical 2D magnetic materials and methods for constructing and characterizing magnetic heterostructures are briefly introduced. Then, magnetic heterostructures composed of magnetic/nonmagnetic and magnetic/magnetic materials are summarized, and recent advances in spintronic devices fabricated using magnetic heterostructures and the device performance are presented. Finally, an outlook for the future development of 2D magnetic heterostructures and spintronic devices is presented.
