Abstract

Low frequency Raman spectra of (Pb_0.97La_0.02)(Zr_0.864Sn_0.04Ti_0.096)O₃ ceramic samples have been studied near cubic to antiferroelectric phase transition at about 200 °C. A set of low frequency soft modes were observed restoring below the transition point, in addition to the known one above 100cm^-1. These modes show strong damping anomalies at the transition point that supposes considerable intermode interactions via dampings.
