Abstract
Pyroeffects, longitudinal and transverse with respect to the direction of preliminary polarization, were investigated in PbZrO3 crystal. In the vicinity of the transient ferroelectric phase, Barkhausen pulses from the residual domains were detected. These pulses occur against the background of the continuous current component related to disappearance of the space charge polarization. Reasons for the diffusion of the phase transitions and also the nature of the residual current observed in the neighbourhood of the intermediate ferroelectric phase are discussed.Keywords
