Abstract

A novel A-site ordered perovskite CaCu₃Pt₄O ₁₂ was synthesized under high pressure and high temperature of 12 GPa and 1250 °C. CaCu₃Pt₄O₁₂ is the first perovskite in which the B site is fully occupied by Pt⁴⁺. The crystal structure refinement based on the synchrotron powder X-ray diffraction data shows that CaCu₃Pt₄O₁₂ crystallizes in the space group Im3(cubic) with a lattice constant of a = 7.48946(10) Å. The magnetic susceptibility data show the antiferromagnetic transition at T _N = 40 K, which is attributed to the magnetic ordering of Cu ²⁺ spins with S = ¹/₂.
