Abstract

Two new double perovskite oxides, Ca₂NiOsO₆ and Sr₂NiOsO₆, have been prepared as polycrystalline powders by solid state synthesis. The two oxides were structurally characterized by variable-temperature powder neutron diffraction. Ca₂NiOsO₆ was found to adopt a monoclinic structure (P₂₁/n), while Sr₂NiOsO₆ was found to be tetragonal (I4/m). Magnetic susceptibility measurements indicate that Ca₂NiOsO₆ orders in a canted antiferromagnetic state at about 175 K while Sr₂NiOsO₆ orders antiferromagnetically at about 50 K.
