EXPERIMENTAL AND AB INITIO STUDY ON VALENCE-BAND STRUCTURE OF SrRuO3

We present experimental and theoretical study on valence-band structure of epitaxial SrRuO3 thin films. Experimentally electronic structure of epitaxial SrRuO3 thin films was obtained from resonant photoemission spectra using synchrotron radiation. Theoretical calculations were performed within density functional theory framework employing generalized gradient approximation for exchange-correlation functionals. A good agreement between experiment and theory indicates the suitability of applied analysis methods.
