After bipolar electric fatigue of bulk lead–zirconate–titanate ceramics, the well known reduced remnant polarization values are observed as well as an asymmetric strain hysteresis reflecting a macroscopic offset polarization. Thermal treatment and high electric fields each liberate the domain system from the microscopic defects responsible for the macroscopic offsets. High electric fields (4 E[sub c]) only allow one to remove the type of pinning center inducing an offset polarization, while thermal treatment also removes more stable agglomerates and rejuvenates the material to almost its original properties. © 2002 American Institute of Physics.

    Poling process is essential for ferroelectric ceramics and crystals. It is traditionally assumed that the one of P[sub S] vectors allowed by symmetry is energetically preferred which is closest to the direction of applied field. It is shown that because of the role of the soft energy this may...
