Abstract
During the investigation of the Barkhausen effect and the reversal current [1] in ferroelectric crystals, it was observed that, together with other factors, the length of time during which the specimens had been kept in a steady electric field has a substantial effect on the polarization reversal process. In this connection, it is of interest to investigate parallely the Barkhausen effect and the reversal current in ferroelectric crystals at various lengths of action of the electric field. In this paper we have investigated the number of Barkhausen jumps, the charge being reversed, the buildup time of the total and irreversible polarization, as well as the starting field for jumps and reversal current as a function of the length of action of the field on specimens of TGS and BaTiO3 single crystals during the quasistatic polarization reversal process.
