Abstract:
X-ray absorption spectroscopy has been applied for a characterization of charge states of cobalt ions of nanostructured GdBaCo2O5.5 complex oxides. The analysis of experimental and theoretical data has allowed establishing a reduction in the oxidation degree from Co3+ to Co2+ for a part of cobalt ions in GdBaCo2O5.5 nanoceramics obtained by torsion under pressure.
