Abstract
The polarization reversal/switching process was investigated in normal and relaxor ferroelectrics and described as a result of field-induced evolution of domain/heterophase structure. Hysteresis loops and elastic light scattering data recorded under the action of field pulses were measured. The development of a heterophase structure in relaxors during “switching” and spontaneous “backswitching” near the phase transition point to the ferroelectric phase is proposed. Particular attention is given to the non-exponential relaxation behaviour of the bias field value in ferroelectrics during periodic alternating sign switching and of scattered light intensity in relaxors during “switching” and spontaneous “backswitching” near the transition point.
