Room-temperature ferromagnetism in two-dimensional transition metal chalcogenides: Strategies and origin

Room-temperature (RT) ferromagnetic atomically thin transition metal chalcogenides (TMCs) provide a novel platform for discovering new physical phenomena in the two-dimensional (2D) limit and developing the next-generation spintronic applications. Recent progress in exploring the RT ferromagnetism in 2D TMCs have attracted significant interest from experimental and theoretical scientists; However, the semi-conducting TMCs are non-magnetic. In parallel, the inconsistency of magnetism between density functional theory (DFT) calculations and experimental results persist in both TMC semiconductors and metals. We review the strategies for RT ferromagnetism in 2D TMC semiconductors and the origin of RT ferro-magnetism in 2D TMC metals, followed by the discussion of promising future directions in the area of RT ferromagnetic 2D TMC materials.
