Microstructure and phase transitions in

Abstract
The microstructure and phase transitions in the perovskite-based ferroelectric lead scandium tantalate, Pb(Sc0.5Ta0.5)O-3 have been investigated by transmission electron microscopy. The effects of ordering of Sc and Ta cations are apparent in reciprocal space as well as in direct space images. High-resolution observations allow direct structure imaging of the domain structure. The structure of the low temperature ferroelectric phase is studied by selected area electron diffraction (SAED) and electron microdiffraction. The relaxer behaviour of this paraelectric-ferroelectric transition is displayed by diffuse intensities in the SAED patterns at temperatures around the Curie point.
