Abstract

The MnO₂ doping effect on ferroelectric phase transitions of CaBi₄Ti₄O₁₅ ceramics has been studied by Raman scattering, dielectric measurements and scanning electron microscope. The Curie temperatures show monotonic decrease as the content of MnO₂ increases. Softeing of low frequency optical modes has been observed for all the compositions, while the Raman scattering decreases markedly as the content of MnO₂ increases.
