Dielectric and Elastic Properties in the Vicinity of a Diffuse Structural Phase Transition in a PZT-Based Multicomponent System

摘要

Dielectric and elastic properties are studied in the vicinity of a diffuse structural phase transition in a PZT-based soft-grained ceramic material with ferroelectric–relaxor properties. Low-temperature phase transition R 3 c → R 3 m between two rhombohedral phases occurs when T < T ~(C). Anomalies in different parameters are observed in the region of the phase transition.
