Abstract
Propagation of the small amplitude elastic bulk waves in piezoelectric single crystals La3Ga5SiO14 deformed by electrostatic field E is considered. Coefficients of controlling of velocities by E depending on parameters of nonlinear electromechanical properties have been obtained for the crystals of 32 group of symmetry. The experimental studies of the field dependencies of elastic wave velocities were carried out. The parameters ai of nonlinear eleotromechanical effects for La3Ga5SiO14 were obtained.Keywords
