Abstract

We present Mn $3 s$ x-ray photoelectron spectra of manganese oxides with the Mn formal valency from $2 +$ to $4 + .$ We found that the ${Sr}^{2 +}$ doping or cation deficiency in manganites do not change the Mn $3 s$ splitting in manganites with the Mn formal valency from $3.0 +$ to $3.3 + .$ We suggest that doping holes are localized in O $2 p$ states.
