The x-ray diffraction spectra of films grown on (a) substrates with Pt buffer layer and (b) YSZ substrates.
Crystal field splitting of Fe sites (300 K). (a) The x-ray absorption spectra corresponding to Fe 2p to Fe 3d excitations. The symbols are the calculated matrix elements from the initial to the final one-electron states. (b) Schematics of the experimental setup. (c) Schematics of the local environment of Fe sites. (d) The crystal splitting extracted from the XAS spectra.
Optical absorption coefficient as a function of photon energy. Inset: as a function of photon energy, which indicates an optical bandgap of 2.0 eV.
Projected density of states for conduction band of with theoretical ground state structure (space group ) and MLWFs (by wien2k software package (Refs. 35 and 36)) with crystal field splitting states characters.
The spin-allowed excited states and the dipole selection rules from the ground state with a linearly polarized photon. Note that both and multiplets contain IR and .
