Executive Summary : | Magnetism is a crucial aspect of technology, with quantum magnetism offering opportunities to investigate complex magnetic phases. Van der Waals materials, a broad family of crystals formed of 2D sheets of densely linked atoms, have grown rapidly, with several unique systems introduced and many more expected. These materials have electrical properties ranging from metal to insulators, including topological insulators. The discovery of graphene, a single layer of graphite easily separated by scotch tape with zero band gap, has led to the exploration of new physical phenomena in various fields. Until recently, 2D magnetic property in atomically thin crystals was lacking in 2D materials. The recent discovery of magnetism in atomic layers has revolutionized the research of 2D van der Waals materials, opening up new possibilities for room temperature technology applications. Van der Waals magnets have advantages over other magnetic systems, such as their stronger intrinsic magnetism. Theoretical predictions of many 2DMMs show good prospects for overcoming issues and producing efficient 2D magnetic materials. The binary chalcogenides class exhibits strong ferromagnetic behavior with good stability at ambient conditions, with an estimated ferromagnetic Curie temperature (TC) in the range of 30-160 K. The single layer of CrSnTe3 reveals TC at 170 K, but no experimental confirmation has been found. There are new opportunities to explore 2D magnetism and multiferroicity in 2D van der Waals materials, and stacking van der Waals heterostructures with interlayer magnetic coupling offers exciting opportunities for emerging new physical properties. |
