Abstract

The temperature dependence of dielectric permittivity was investigated for the barium zirconium titanate solid solution system [BZT, Ba (Zrx Ti1-x) O3 0.25x0.5]. The dielectric relaxation behavior was observed in these ferroelectrics with diffused phase transition. In contrast to the canonical relaxors such as Pb (Mg1/3 Nb2/3) O3, the diffused phase transition of BZT could not be well described by the popular modified Curie-Weiss law. Quasiferroelectric state theory was introduced to explain the dielectric results of the BZT relaxors.
