Air‐Stable 2D Intrinsic Ferromagnetic Ta3FeS6 with Four Months Durability

Abstract 2D ferromagnetic materials provide an important platform for the fundamental magnetic research at atomic‐layer thickness which has great prospects for next‐generation spintronic devices. However, the currently discovered 2D ferromagnetic materials (such as, CrI3, Cr2Ge2Te6, and Fe3GeTe2) su...
