The strains induced by a large electric field were measured for the (Pb La) (Zr Ti)O3 solid solution system. Three types of strains which were involved with an inverse piezoelectric effect, an electrostriction and a forced phase transition, were measured. A strain of 0.24%, large enough for high performance actuators, was observed under 40 kV/cm for the 8.4/70/30 composition near the rhombohedral-cubic phase boundary.
