Abstract
The strains induced by a large electric field were measured for the (P b La) (Zr Ti)O-3 solid solution system. Three types of strains which w ere involved with an inverse piezoelectric effect: an electrostriction and a forced phase transition, were measured. A strain of 0.24%, larg e enough for high performance actuators, was observed under 40 kV/cm f or the 8.4/70/30 composition near the rhombohedral-cubic phase boundar y.
