Abstract Bi{sub 4}Ti{sub 3}O{sub 12}, (BTO) a Bi-layered perovskite oxide, shows fatigue after repeated ferroelectric polarization reversals. On the other hand, Bi{sub 3.25}La{sub 0.75}Ti{sub 3}O{sub 12} (BLT) is fatigue free. From an extensive transmission electron microscopy study, it was found that there is a high density of antiphase boundaries (APBs) in BLT like in the fatigue-free SrBi{sub 2}Ta{sub 2}O{sub 9} but not in BTO. It is proposed that the existence of APBs possibly plays a key role in the fatigue-free behavior of Bi-layered perovskite oxides. {copyright} 2001 American Institute of Physics.
