Abstract

A novel A-site ordered perovskite CaCu(3)Pt(4)O(12) was synthesized under high pressure and high temperature of 12 GPa and 1250 degrees C. CaCu(3)Pt(4)O(12) is the first perovskite in which the B site is fully occupied by Pt(4+). The crystal structure refinement based on the synchrotron powder X-ray diffraction data shows that CaCu(3)Pt(4)O(12) crystallizes in the space group Im3 (cubic) with a lattice constant of a = 7.48946(10) A. 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.
