Abstract:

Structure, dielectric and ferroelectric properties of Bi doped Bi-BCT and Bi-BCST perovskite ceramics prepared through a solid-state reaction technique were investigated. Results show that there is a diffusional aging effect in Bi-BCT ceramics, and that point-defect-mediated reversible domain switching mechanism may be responsible for the double hysteresis loops observed in Bi-BCT ceramics. It is expected that the abnormal dielectric behavior of Bi-BSCT ceramics can be explained by a point-defect-mediated reversible domain switching mechanism.
