Development of Intrinsic Room-Temperature 2D Ferromagnetic Crystals for 2D Spintronics

  • Two-dimensional (2D) ferromagnetic crystals with fascinating optical and electrical properties are crucial for nanotechnology and have a wide variety of applications in spintronics. However, low Curie temperatures of most 2D ferromagnetic crystals seriously hinder their practical applications, thus searching for intrinsic room-temperature 2D ferromagnetic crystals is of great importance for development of information technology. Fortunately, progresses have been achieved in the last few years. Here we review recent advances in the field of intrinsic room-temperature 2D ferromagnetic crystals and introduce their applications in spintronic devices based on van der Waals heterostructures. Finally, the remaining challenge and future perspective on the development direction of intrinsic room-temperature 2D ferromagnetic crystals for 2D spintronics and van der Waals spintronics are briefly summarized.
