Abstract The ferroelectric switching mechanism in strontium bismuth tantalate [SrBi{sub 2}Ta{sub 2}O{sub 9} (SBT)] has been studied using in situ transmission electron microscopy observations of the nucleation and growth of polarization domains, such as 180{sup o} and 90{sup o} domains. Thank to this high density of the antiphase boundary (APB), a switching mechanism in SBT based on the nucleation of new polarization domains at APBs as well as the electrode interfaces put forward and the fatigue-free behavior of SBT with a platinum electrode is explained. {copyright} 2001 American Institute of Physics.
