Аннотация:
Low frequency Raman spectra of (Pb0.97La0.02)(Zr0.864Sn0.04Ti0.096)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 100 cm–1. These modes show strong damping anomalies at the transition point that supposes considerable inter mode interactions via dampings.
