Towards an accurate structural phase diagram for the novel BiScO3-PbTiO3 ferr...
The aim of this experiment is to determine accurately the crystal structures of phases in the (1-x)BiScO3-xPbTiO3 (BST-PT) perovskite phase diagram, particularly in the vicinity... -
The structures of PZT in its ¿rhombohedral¿ phases and their dependence on th...
In the piezoelectric ceramic material PbZrxTi1-xO3 (PZT) there is controversy about the structure of PZT at the Zr-rich end. This region has always been considered to be of... -
Influence of compressive stress and electric field on the shape memory effect...
The proposed experiment involves monitoring the depolarisation behaviour of rhombohedral PZT (lead zirconate titanate) ceramics caused by ferroelectric domain switching during...
