Abstract

The complex perovskite ferroelectric/antiferroelectric of (Pb _1-1.5xLa_x)(Zr_0.42Sn _0.40Ti_0.18)O₃ (PLZST) ceramics have been investigated by Raman scattering spectra from 77 to 480 K. It was found that phase transition occurs between La composition of 2.6% and 2.8% for PLZST ceramics. Softing of A₁(TO₁) mode and dramatic changes of relative strength from E(TO₂) mode are observed at morphotropic phase boundary (MPB). Moreover, it was found that MPB characteristic shows a wider and lower trend of temperature region with increasing La composition. This could be ascribed to the diminishment of the energy barrier and increment of A-cation entropy.
