Ferromagnetic van der Waals Crystal VI<sub>3</sub>
We report structural properties, physical properties, and the electronic structure of van der Waals (vdW) crystal VI3. Detailed analysis reveals that VI3 exhibits a structural transition from monoclinic C2/ m to rhombohedral R3̅ at Ts ≈ 79 K, similar to CrX3 (X = Cl, Br, I). Below Ts, a long-range …
