Times Cited Count:2 Percentile:9.71(Physics, Applied)Resonant X-ray inelastic scattering experiments have been performed at the Ba-L edge in ferroelectric BaTiO using synchrotron radiation at the BL15XU of SPring-8. An X-ray absorption spectrum of this material was found to be broader than non-ferroelectric BaSO. Molecular orbital calculations showed the formation of Ba-O bands in BaTiO, suggesting an important role of the Ba-O hybridization in the ferroelectric transition of this material. X-ray emission spectra at the edge showed a localized character of Ba-5d orbitals in BaTiO in spite of the hybridization with O-3p. A few possible applications of the measurement will be also discussed.
