Ageing of (Pb, La)(Zr, Ti)O3 ferroelectric ceramics and the space charge arising on hot poling

Abstract

Polarization-temperature diagrams of pyroelectric charge and the decrease of remanent polarization (P R) at constant temperature are investigated in PLZT 8/65/35 ceramic samples. The arousal of space charge is shown to be unlike that of pyroelectric charge and highly dependent on poling temperature. This charge, measured by the thermally stimulated current in hot poled samples, obeys the dielectric discharge lawi=kt −n and is also responsible for the recovery ofP R after the samples have been thermically depoled in part, in contrast with samples poled at room temperature. The evolution ofP R follows the lawi =kt -n Int where the slopeB decreases with poling temperature when the sign ofP R is that of the former polarization. The ageing behaviour is correlated with the space charge that arises on hot poling.
