Abstract
We report on the heteroepitaxial stabilization of YCrO3 ultra-thin films on LSAT (001) substrate. Using a combination of resonant X-ray absorption spectroscopy (XAS) and atomic multiplet cluster calculation, the electronic structure of YCrO3 thin film was investigated. Polarization dependent Cr L3,2 edge XAS measurements reveal the presence of x-ray linear dichroism spectrum uncharacteristic of a 3d3 electronic system in an octahedral crystal field. Atomic multiplet calculation demonstrates the critical importance of charge transfer energy, coulomb correlation strength, and hopping interaction in realizing this dichroism spectrum.
