Abstract
The electronic structure of La 0.65Pb 0.35MnO 3 has been studied by X-ray photoemission spectroscopy (XPS). The valence band spectrum is compared with ab-initio electronic structure calculations using linearized muffin–tin orbital (LMTO) method. The XPS measurements, and the theoretical band-structure calculations for La 0.75Pb 0.25MnO 3, show that the electronic structure of La 0.65Pb 0.35MnO 3 compound consists mainly of Mn 3d and O 2p states. In addition, the Mn 3d and O 2p states are hybridized over the whole valence band. States of 3d characters localized in Mn site predominate near the top of the valence band. We have found a good agreement between the experimental valence band spectra and theoretical calculations.
