Abstract

Ultrawideband dielectric spectroscopy analysis of barium zirconate titanate (BaZrxTi1-xO3BZT) ceramics at different temperatures disclosed the contribution of both the dipole and the ionic polarizations to permittivity at around dielectric maximum temperature (T m). In BaZr0.25Ti0.75O3 ceramics, the permittivity around Tm is dominated by the temperature dependence of the permittivity determined by the dipole polarization (εdipole). In relaxor ferroelectrics, the diffuse dielectric response around Tm could be derived from the temperature dependence of εdipole. The variation of εdipole with temperature could be also explained by the growth process of polar nanoregions (PNRs) and the damping process of the thermal fluctuation of dipoles in PNRs.
