Abstract

By means of ferroelectric differential hysteresis loop spectra, the polarization fatigue of Ba 0.99 Sr 0.01 TiO3 ceramics was carefully studied. The effects of conductance, paraelectrics and pure ferroelectrics could be definitely separated. The results show that the polarization fatigue arose from 180° domain appears much faster than that arose from 90° domain. Ferroelectric differential loop spectra are proved to be a much more powerful method to describe polarization fatigue than traditional hysteresis loop.

Key words： ferroelectricity; fatigue; differential hysteresis loop; BST
