Abstract

Synchrotron X-ray experiments on rhombohedral PZT ceramics with electric fields in between -2.4 and 2.4 kV/mm(-1) were performed in order to seperate between field-induced ferroelectric-ferroelastic and piezoelectric effects. The results are compared with results of macroscopic measurements. Additionally the influence of different dopands (La, Ag) and grain sizes on the intrinsic piezoelectric effect are investigated and coercive field strength are given.
