Abstract

The influence of a static external electric field on the electroacoustic properties of the piezoelectric ceramic, PZT-4, has been investigated. The velocity of the acoustic waves were found to depend strongly on the applid. electric field. Both linear and nonlinear velocity variations as a function of the applied electric field were observed. In particular, under the influence of an electric field along the 0011 axis 1001 axis, the changes of the veloci are linear. direction the changes. in the acoustic wave velocity in the [loo] direction are nonlinear. PZT-4 displays a very strong electroacoustic effect, signifgicantly greater than that known for LiNbO , one of the strongest known nonlinear piezoelecTric materials. and a longitudinal wave propagating a I ong the t owever, for the electric field along t 3: e [OlO]
