Abstract

Resonant inelastic X-ray scattering (RIXS) measurements have been carried out at the Ba-L3 absorption edge on ferroelectric BaTiO3 for the first time. The absorption spectrum was measured in the partial fluorescence yield mode, by monitoring the intensity of the maximum of the Ba-Lα1 line through the Ba-L3 edge. The main peak, which reflects the unoccupied density of Ba 5d states, is found to be narrow, although broad shoulderlike tails appear towards both low and high energies. Using band structure calculations, these tails are ascribed to the strong hybridization between unoccupied Ba 5d and O 2p bands. Hybridization notwithstanding, the Ba 5d band is shown to retain a localized character, on the basis of the incident energy dependence of the Ba-Lα1 RIXS spectra.
