Abstract: Resonant soft X-ray scattering spectra of aLa0.5Ca0.5MnO3thin film were measured at varying energies of the incident photon beam across Mn2pthresholds. The data are analyzed within the framework of the Anderson impurity model and full multiplet theory. The scattering profiles of the film are reasonably well reproduced by model calculations for theMn3+system, in contrast to the absorption spectrum at the MnL2,3edge for which the contribution of theMn4+sublattice is required to be taken into account. The obtained agreement between calculations and experiment indicates that in this case resonant inelastic scattering mainly probes the local electronic structure at theMn3+sites in theLa0.5Ca0.5MnO3film. In turn,Mn4+sites mainly contribute to ordinaryLα,βX-ray emission due to relaxations in the intermediate state of the spectroscopic process. Such a situation can occur when the system favors a phase separation rather than checkerboard charge ordering ofMn3+andMn4+sites.
