Determining the valence state of manganese ions in complex oxides La1–xCaxMnO3 (x = 0.5, 0.7, 0.85, and 0.9) based on Mn2p and Mn3s X-ray photoelectron spectra

Determining the valence state of manganese ions in complex oxides La1–xCaxMnO3 (x = 0.5, 0.7, 0.85, and 0.9) based on Mn2p and Mn3s X-ray photoelectron spectra

The valence state of manganese ions in complex oxides La 1– x Ca x MnO 3 ( x = 0.5, 0.7, 0.85, and 0.9) is studied on the basis of Mn2 p and Mn3 s X-ray photoelectron spectra. It is shown that manganese ions have the valence of Mn 3+ and Mn 4+ in the studied compounds. The relative Mn 3+ /Mn 4+ cont...

Zusammenfassung:The valence state of manganese ions in complex oxides La 1– x Ca x MnO 3 ( x = 0.5, 0.7, 0.85, and 0.9) is studied on the basis of Mn2 p and Mn3 s X-ray photoelectron spectra. It is shown that manganese ions have the valence of Mn 3+ and Mn 4+ in the studied compounds. The relative Mn 3+ /Mn 4+ content is determined.
