Rejuvenation of Ferroelectric Fatigue in Modified Lead Zirconate Titanate Ceramics Near Tetragonal-Rhombohedral Morphotropic Phase Boundary,
Abstract
Rejuvenation of ferroelectric fatigue is investigated in modified lead zirconate titanate ferroelectric ceramics near the tetragonal-rhombohedral morphotropic phase boundary. Ferroelectric fatigue rejuvenates with changes in the applied electric field direction. Spontaneous rejuvenation occurs in the absence of an electric field. A coupling among the applied electric field, oxygen vacancy related defect dipoles, and spontaneous polarizations is proposed to explain ferroelectric fatigue and rejuvenation.
