Reversive Dielectric Response in xPZN-(1 − x) PSN Ceramics
2006
The effects of bias fields E= on dielectric response of xPbZn1/3Nb2/3O3-(1 − x)PbSc1/2 Nb1/2O3 ferroelectric solid solutions of x = 0, 0.05, 0.2, and 0.5 studied at temperatures of diffused phase transitions are reported. The thermal interval of the existence of a relaxor phase in the system is found to shrink with the concentration of PbZn1/3Nb2/3O3. The change of the ratio of zinc-lead and scandium-lead niobate components is deduced to change the features of the transition to polarised state from first-order to second-order transition.
Dielectric Properties of the 0.05PZN–0.95PSN Ferroelectric Ceramics at Low and Infra-Low Frequencies
2005
Manifestations of relaxor properties similar to those observed in lead magnesium niobates are reported in the 0.05PZN–0.95PSN ceramic solid solution system. Behaviour of the effective dielectric permittivity and dielectric loss with temperature at frequencies between 0.1 and 10 Hz at different field amplitudes are examined in ceramic samples of 0.05PZN–0.95PSN. The temperature T m of the dielectric permittivity maximum is observed to decrease with the increase of the measuring field amplitude E o . Dependence of T m on frequency at strong and weak fields is observed to follow the Fogel-Fulcher law, and the Fogel-Fulcher temperature is found to decrease with the increase of E o . Results of …
