Abstract

The lattice dynamical properties of (Pb_1-xCa_x) TiO₃ ceramics were investigated by Raman scattering. The low-frequency spectra show the strong composition and temperature dependences. The composition dependence of Raman spectra at room temperature is different from the previous work [S.-Y. Kuo, C.-T. Li and W.-F. Hsieh, Phys. Rev. B 69, 184104 (2004).]. This difference is probably attributed to the aging effect of MnO doping. Temperature dependence of Raman spectra of (Pb_0.75Ca _0.25)TiO₃ behaves as expected by the selection rule and the lowest-frequency peak softened and broadened as approaching T_c.
