Abstract: A quadruple perovskite oxide CaCu3Co2Re2O12 was synthesized by high-pressure annealing. This compound crystallizes in an A- and B-site ordered quadruple perovskite structure with space group Pn-3. The charge combination is determined to be CaCu2+3Co2+2Re6+2O12 by bond valence sum analysis and x-ray absorption spectroscopy. In contrast to other isostructural ACu3B2B2′O12 compounds with a single magnetic transition, a long-range antiferromagnetic phase transition originating from the A′-site Cu2+ sublattice is found to occur at TN≈28K. Subsequently, the spin coupling between the B-site Co2+ and B′-site Re6+ ions contributes to a ferrimagnetic transition around TC≈20K. Strong electrical insulating behavior is identified by optical measurement with an energy gap of approximately 3.75 eV. The mechanisms of the spin interactions are discussed in detail. © 2021 American Physical Society.
