- Abstract
- The electronic structure of the electron-doped manganite La0.7Ce0.3MnO3 (LCeMO) has been investigated by performing the band calculations with the local spin-density functional approximation (LSDA), which are then compared to the photoemission spectroscopy (PES) data. In order to investigate the effect of the Mn 3d on-site Coulomb correlation on the electronic structure of LCeMO, we have calculated the Mn 3d partial density of states (PDOS) by performing the LSDA+U calculations. Our calculations show that the Mn 3d on-site Coulomb correlation accounts for the major features in the experimental PES spectra, such as the peak positions and the reduced spectral weight near the Fermi level.
