抄録

In this report, we present the characterization of CaCo^IVO₃ perovskite thin films prepared from the oxidation of CaCo^IIIO_2.5 brownmillerite films using a NaClO solution. The oxidation state and octahedral coordination of cobalt in CaCoO₃ is confirmed by comparing with that of SrCoO₃ via Co-L_2,3 edge soft X-ray absorption spectroscopy.
