Robust intralayer antiferromagnetism and tricriticality in the van der Waals compound VBr3

Formation of Domains within a Lower-to-Higher Symmetry Structural Transition in CrI3

“…CrI 3 and CrBr 3 are ferromagnetic (FM) with T c = 61 5,6 and 37 K, 7 respectively, whereas CrCl 3 shows antiferromagnetic (AFM) order below T N = 17 K. 8,9 Monolayers of all three compounds were reported to be FMs. 10−12 The vanadium counterparts are FM (VI 3 13,14 ) and AFM (VBr 3 15,16 and VCl 3 17 ). The high-temperature (HT) structure of the three VX 3 compounds is the rhombohedral one (R-3) which undergoes a structural transition with cooling through the transition temperature T s (which lies between 79 and 100 K for all three VX 3 compounds 17 ).…”
