Mixed valence states in lead perovskites: A possible avenue to produce next-generation materials

Scientists at Tokyo Institute of Technology, the Kanagawa Academy of Science and Technology have reported an unusual charge distribution of Pb2+Pb4+3Co2+2Co3+2O12 for a perovskite PbCoO3 synthesized at 12 GPa, with charge orderings in the A and B sites of an ABO3 perovskite. This strategy can possibly lead to the production of next-generation materials with fascinating properties such as superconductivity, colossal magnetoresistance, and high thermopower.
