Two-Dimensional S = 1 Quantum Antiferromagnet (NiCl)Sr2Ta3O10
Abstract
A topotactic ion-exchange reaction of a layered perovskite RbSr2Ta3O10 with NiCl2 yielded a novel two-dimensional nickel-oxyhalide (NiCl)Sr2Ta3O10, the first S = 1 compound among related series of metal-oxyhalides. The room temperature structure is isostructural with (CuCl)Ca2Nb3O10 adopting the space group P4/mmm. We found a possible structural transition at 230 K that does not lead to drastic changes in magnetic character such as nickel …
