Abstract

(Sr0.7Bi0.2)TiO3 ceramics were fabricated by a solid state reaction, and a wideband dielectric spectrum was measured for understanding the microscopic polarization mechanism of (Sr0.7Bi0.2)TiO3 ceramics. It was revealed that the dielectric permittivity of (Sr0.7Bi0.2)TiO3 ceramics at 25°C was determined by dipole polarization as well as ionic polarization, whereas the permittivity of SrTiO3 is mainly determined only by ionic polarization. The temperature dependence of permittivity suggested that (Sr0.7Bi0.2)TiO3 ceramics belongs to ferroelectric relaxor, in which off-center Bi3+ ions contribute to the formation of polar nanoregions (PNRs). The origin of the dipole polarization is considered the dipole fluctuations of PNRs. On the other hand, the ionic polarization of (Sr0.7Bi0.2)TiO3 ceramics was suppressed by an influence of Sr-site vacancy, compared to that of SrTiO3. High permittivity of (Sr0.7Bi0.2)TiO3 ceramics is mainly due to the dipole polarization associated with dipole fluctuation of PNRs.
