“…44 On the other hand, several new CrX 2 (X = O, S, Se) orthorhombic monolayers are predicted to exhibit intrinsic ferromagnetism, high T C , and magnetoelastic coupling. 45 Furthermore, several 2D Janus Cr-based TMDs, namely CrXY (X a Y = S, Se, and Te), with 1T and 2H phases, are predicted to have a large Rashba spin splitting, piezoelectric response, and inherent ferromagnetism. 41,46,47 Taking this into account, new Janus Cr-based dichalcogenides have a reasonable expectation of becoming ferromagnets with interesting properties.…”
