Determination of charge states of cobalt ions in nanostructured GdBaCo2O5.5 cobaltites by means of X-ray absorption spectroscopy

X-ray absorption spectroscopy has been applied for a characterization of charge states of cobalt ions of nanostructured GdBaCo 2 O 5.5 complex oxides. The analysis of experimental and theoretical data has allowed establishing a reduction in the oxidation degree from Co 3+ to Co 2+ for a part of coba...

Description
Summary:X-ray absorption spectroscopy has been applied for a characterization of charge states of cobalt ions of nanostructured GdBaCo 2 O 5.5 complex oxides. The analysis of experimental and theoretical data has allowed establishing a reduction in the oxidation degree from Co 3+ to Co 2+ for a part of cobalt ions in GdBaCo 2 O 5.5 nanoceramics obtained by torsion under pressure.
