TY - JOUR TI - Relaxation currents in the non-morphotropic region of PZT-PFS ferroelectric ceramics AU - Osak, Andrzej TI - Relaxation currents in the non-morphotropic region of PZT-PFS ferroelectric ceramics AB - Studies on the dielectric relaxation currents in the non-morphotropic region of PZT-PFS are presented. Transient polarization and depolarization currents were measured at different poling fields (0.02–20 kV/cm) and different temperatures (77–473 K). The activation energies were calculated. The defect dipole complex (FeTiZr–VÖ) and reorientation cluster dipole models are proposed to explain the observed relaxation behaviour in PZT-PFS.
