Abstract
The domain structure of the bismuth layered ferroelectric SrBi2 Ta2 O9 (SBT) has been studied by group theoretical methods. It is shown that there should exist five types of domain pair independent of one another in SBT, namely: (1) translational domain pairs; (2) 180° (rotational) domain pairs; (3) translational -180° domain pairs; (4) 90° domain pairs; (5) translational -90° domain pairs. In addition, some experimental results are briefly discussed.Keywords
