description

The present study is focused on the behaviour of polarization and depolarization currents and processes of the slow relaxation of polarization within the range of temperatures where the anomalies are displayed by the materials. Results of the study are discussed with regard to possible existence of defect complexes in disordered ferroelectrics.
