Abstract

Domain structure of the bismuth layered ferroelectric SrBi2Ta2O9(SBT) ceramics has been studied by space group analysis and transmission electron microscope (TEM) observation. The space group analysis shows that there should exist five types of domain walls in SBT, namely: (1) antiphase boundary (APB); (2) 180°; (3) APB combined with 180°; (4) 90°; (5) APB combined with 90°. The 90° domain wall has been confirmed by TEM observation. Preliminary evidences for APB have also been obtained.
