摘要
Relaxor behavior has been found in a new solid solution between complex perovskite Ba(Zn1/3Nb2/3S)O3 (BZN) and ferroelectric PbTiO3 (PT), prepared by solid state reactions. A strong dispersion of the maximum of dielectric permittivity (ε′) appears around the temperature of Tm, which shifts toward higher temperatures with increasing frequency. The variation of Tm with frequency follows the Vogel-Fulcher relationship. The variation of 1/ε′ with temperature above Tm deviates from the Curie-Weiss law, but satisfies a Lorentz-type function. The relaxor behavior becomes weaker upon increasing PT-content.
