Abstract
The electronic structure of the single crystal La0.7Sr0.3MnO3 in ferromagnetic metallic phase has been investigated by photoelectron spectroscopy. Valence band spectra were measured at 40 K for various photon energies, in the range of 45–70 eV. The Mn 3d partial density of states was derived from resonant photoemission near the Mn 3p–3d threshold. Besides the occupied 3d states, resonant photoemission data has provided information about the unoccupied 3d states. The value of the on-site Coulomb interaction strength (correlation energy) was estimated to be 6.7 eV.
