Abstract
The influence of the thermal and electrical prehistory on the behaviou r of polarization and depolarization currents in relaxer ferroelectric Sr0.75Ba0.25Nb2O6 (SBN) in the range of diffuse phase transition temp eratures (relaxer phase - RP) was investigated. We consider the assump tion that in the process of long-time isothermal (one or two months at T=const) or slow cooling big polar clusters - ''microelectrets'' are formed. By heating the sample these microelectrets are destroyed and t hat leads to the appearance of depolarization currents.
