摘要
We report the soft X-ray absorption spectroscopy (XAS) on pulsed laser deposition (PLD) grown epitaxial BaTiO3 thin film on (001) oriented SrTiO3 substrate. X-ray diffraction studies confirm that film is grown along the [00l] direction and is compressed along surface normal. XAS around O K edge and Ti L-3,L-2 edges performed on BaTiO3 thin film along with bulk BaTiO3 depicts considerable changes in crystal field parameters in thin film form due to strain present in the film. Modifications observed in t(2g) and c(g) sub bands of Ti ions are explained considering structural anisotropies present in the thin film.
