Abstract

A topotactic ion-exchange reaction of a layered perovskite RbSr ₂Ta₃O₁₀ with NiCl₂ yielded a novel two-dimensional nickel-oxyhalide (NiCl)Sr₂Ta₃O ₁₀, 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 clustering. Despite a large Weiss temperature of θ =-125 K, magnetic long-range order is significantly suppressed down to T_N1 ≈ 50 K because of two-dimensionality and strong frustration. The magnetically ordered state below T_N1 has a partial volume fraction coexisting with a paramagnetic component, followed by complete long-range ordering below T_N2 = 20 K. The reaction process and requirement will also be discussed.
