Abstract
▶ Fe2p, Fe3p, and Fe3s XPS in single-crystal BiFeO3 and PbFe1/2Nb1/2O3, are measured. ▶ Single-crystal multiferroics and Fe2O3 have the Fe ions only in the Fe3+ valence state. ▶ BaFe1/2Nb1/2O3 ceramic samples with various Fe2+/Fe3+ abundances are synthesized. ▶ An approximate method to determine the Fe2+/Fe3+ abundances is suggested.
