X-ray photoemission spectra of La0.7Sr0.3MnO3 perovskite
Source abstract
Abstract
Abstract X-ray photoemission (XPS) measurements of the core levels and valence electronic structure of La0.7Sr0.3MnO3 are presented. The ferromagnetic phase La0.7Sr0.3MnO3 is half-metallic, which is important in the relation to colossal magnetoresistance properties of this compound. Comparing XPS measurements, and the LMTO band-structure calculations for La0.75Sr0.25MnO3, one concludes that the electronic structure of La0.7Sr0.3MnO3 compound consists mainly Mn 3d and O 2p states. In addition, the Mn 3d and O 2p states are hybridized over whole valence band. States of 3d character localized in Mn site predominate near the top of the valence band.
