“…However, exploration of intrinsic 2D half-metallic FM materials with a room-temperature T C , sizable MAE, and multiferroic coupling is still required. 2D transition-metal dichalcogenides (TMDs), with diversified polymorphs and interesting electronic and magnetic properties, 28 have attracted considerable attention. 29 In addition to the widely studied traditional phases (e.g., 1T and 2H), at least five new phases (e.g., 1T 0 0 0 -MoS 2 , 30 2M-WS 2 , 31 pentagonal PdSe 2 , 32 1S-NbX 2 (X = S, Se, and Te), 33 and pentagonal CoS 2 34 ) have been proposed using experiments and calculations, which exhibit distinct properties, from semiconductivity or superconductivity to antiferromagnetism.…”
