Abstract
A solid solution of (1-x) Pb(Mg1/3Nb2/3)O3-xBi(Zn2/3Nb1/3)O3 [(1-x)PMN-xBZN)] has been prepared in the form of ceramics with x = 0-0.20 by solid state reaction method. The crystal structure and dielectric properties are investigated. An enhanced relaxor behavior is found when incorporating BZN into canonical relaxor PMN due to the increased chemical disorder. The high temperature slope of dielectric constant as a function of temperature is consistent with the empirical quadratic law. The frequency dependence of the temperature of the dielectric maximum follows the Vogel-Fulcher (V-F) law.
