Low Frequency Raman Scattering in BaTiO3 Crystal

The central peak (CP) in Raman scattering in BTO crystals was investigated in wide spectral and temperature ranges. The identical CP properties both in the VV and the VH scattering geometries, best fitting of low-frequency Raman spectra by the Lorentz function, and obtaining the typical temperature dependences for the CP amplitude and width support the relaxation nature of CP in the BTO crystals.
