Résumé en anglais

The dielectric permittivity as a function of temperature at frequencies from 10-2 to to 105 Hz is studied and parameterized in the perovskite Ba(Ti0.675Zr0.325)O3 ceramics. The features characteristic of relaxor ferroelectrics are found, namely, the Lorenz-type temperature dependence at high-temperature slope of the real permittivity peak, the Curie-Weiss law observed at temperatures much higher than the temperature of the peak, the Vogel-Fulcher scaling of the temperature/frequency dependencies of the permittivity. However, scaling characteristics differ from those in classical complex perovskite relaxors suggesting different origin of dielectric relaxation.< Réduire
