Broad Doublet and Plasmon Peak in Perovskite-Type Oxides
The 180° light scattering experiment has been performed in a Nb-doped SrTi 16 O 3 sample. The spectral intensity of a broad doublet (BD) is found to be very weak, supporting the reported hypothesis that a partially softened transverse acoustic mode is the physical origin of the BD. In addition to th...
