2D van der Waals magnets: From fundamental physics to applications
Scientific discovery is often described as walking into a dark room and turning on the light. The discovery of 2D magnetism in van der Waals materials in 2016 was one such leap forward, removing one spatial dimension from macroscopic materials. The study of 2D magnets has challenged established theories and uncovered new phenomena. This review summarizes the current state of knowledge of magnetic phenomena in 2D van der Waals materials. The field encompasses not just the traditional study of ferromagnets and antiferromagnets but also topology, quantum and nonequilibrium dynamics, Floquet effects, magnons and spintronics, and the interaction of magnetism with light, phonons, and electric fields (multiferroics). The field is actively evolving, expanding theoretical understanding, materials capabilities, and experimental phenomenology, while opening new directions for application.
