X-ray photoelectron spectroscopy study of the ionic configuration of the spinel CuMnCoO4

Abstract
X-ray photoelectron spectra are reported for the spinels CuMnCoO4, CoMn2O4, Co2MnO4 and CoZnMnO4, from which the following ionic configurations can be induced: Cu0.65+Mn0.353+(Cu0.352+Co3+Mn0.65)O4, Co2+(Mn23+)O4, Co2+(Co3+Mn3+)O4 and Zn(Co3+Mn3+)O4.
