Abstract
The influences of perpendicular compressive stress on the ferroelectric properties of ( 1 − x )Pb(In 1/2Nb 1/2)O 3– xPbTiO 3 ( x = 0.1 – 0.4 ) ceramics were investigated in this study. In general, with increasing compressive stress the coercive field and the dissipation energy of the ceramics were seen to increase. The stress-induced changes in the polarization, however, depended significantly on ceramic compositions. The observations were mainly interpreted in terms of competing influence of the domain switching through non-180° domain walls, clamping of domain walls, and the stress-induced decrease in the switchable part of spontaneous polarization.
