Abstract

We have carried out a combined acoustic emission (AE) and dielectric permittivity study of the xPb (Zr_1/2 Ti_1/2) O₃ - (1-x) Pb (Ni_1/3 Nb_2/3) O₃ relaxor ferroelectric ceramics with compositions x=0.7-0.9 corresponding to its morphotropic phase boundary. Temperatures of all phase transitions occurring on heating are identified accurately by AE, and a direct transition between the low-temperature (rhombohedral) and high-temperature (pseudocubic) relaxor phases is found. The AE peak intensity is generally proportional to the temperature derivative of the dielectric permittivity, in agreement with a model proposed for a thermally cycled small elastic dipole.
