Paper Abstract

Manifestation of relaxor properties in the xPbZn1/3Nb2/3O3-(1-x)PbSc1/2Nb1/203 ceramic solid solution system, similar to those observed in lead magnesium niobates, are reported. Dependence of the effective dielectric permittivity and dielectric loss on the temperature at frequencies of 0.1-10 Hz and different measuring field amplitudes E0 are examined ceramic samples of 0.05PbZn1/3Nb2/3O3-0.95PbSc1/2Nb1/203. It is demonstrated that the temperature at which the dielectric permittivity has a maximum, Tm, decreases with the increase of E0. The dependence of Tm on the frequency in both strong and weak fields is shown to follow the Vogel-Fulcher law, with Voger-Fulcher temperature decreasing with the increase of E0. The results of the dielectric studies in the xPbZn1/3Nb2/3O3-(1-x)PbSc1/2Nb1/203 system are discussed in terms of the transition from the paraelectric to ferroelectric phase through the relaxor and glass states.
