Resonant Inelastic Scattering at the L Edge of Ti in Barium Strontium Titanate by Soft-x-ray–Fluorescence Spectroscopy

Document Type



Photon-excited Ti L fluorescence spectra were measured for cubic barium strontium titanate (BSTO) using tunable synchrotron radiation near the Ti L-edge. Elastic (recombination) peaks were observed around Ti L3 and L2 resonances, especially strong at the L3 resonance, while inelastic peaks were observed from well below the resonance and showed complex features at the excitation energies between the Ti L3 and L2 resonances. The measured spectra were explained based on radiative and non-radiative electronic processes near the Ti-L2,3 edge in the titanate
