Abstract
It has been shown that the hysteresis loop of the uniaxial triglycine selenate ferroelectriccan be gradually suppressed in an inhomogeneous electric field not parallel to theferroelectric axis. Such a field was generated by a constant electric potential applied tosilver paste measurement electrodes painted on a single-crystal sample of the form of asmall round plate with an additionally attached grounded silver side (ring) electrode. Nochanges in the coercive field were visible during the remanent polarization decay over time.A reduction of remanent polarization persisted for many days after disconnecting theinhomogeneous electric field if no alternating electric field was applied. The originaldielectric properties could be easily restored by annealing the sample above the criticaltemperature. The mathematical formula for the remanent polarization decay in time isdiscussed.
