2005) Dielectric Properties of the 0.05PZN-0.95PSN 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 the dielectric studies are discussed in terms of transition from paraelectric to ferroelectric phase through relaxor and glass states in the xPZN-(1 − x)PSN solid solution system.
