Кл.слова (ненормированные):
Acoustic wave transmission -- Anisotropy -- Electric field effects -- Lanthanum compounds -- Piezoelectric materials -- Pressure effects -- Thermal effects -- Piezoelectric single crystals -- Single crystals
Аннотация: On the fundamental of our original experimental results the full set of tensorial components of linear and nonlinear electromechanical properties and temperature coefficients of material properties for La3Ga5SiO14 piezoelectric crystals have been obtained. These data were used for the analysis of influence of static electrical field and of uniaxial homogeneous mechanical pressure on the propagation anisotropy of acoustic waves superposed by the temperature variations.

Non-linear piezoelectricity in sillenite structure crystals
/ K. S. Aleksandrov [и др.] // Ferroelectrics. - 1982. - Vol. 41, Is. 1. - P. 27-33
. - ISSN 0015-0193
Аннотация: Propagation of small amplitude elastic waves in piezoelectric media deformed by the electrostatic field has been considered. Green-Christoffel equations describing the propagation of elastic waves in crystals with the biasing electrostatic field have been obtained. The experimental studies of the field dependence on elastic wave velocities for a number of sillenite structure crystals have been carried out. Non-linear piezoelectric coefficients for Bi//1//2GeO//2//0, Bi//1//2SiO//2//0 have been obtained.

Nonlinear electromechanical properties of sillenite and eulytine single crystals
/ K. S. Aleksandrov [et al.] // Ferroelectrics. - 1985. - Vol. 64, Is. 1. - P. 37-38, DOI 10.1080/00150198508018692

Аннотация: The study of nonlinear electromechanical properties (NEMP) of piezoelectrics has recently been stimulated both by the progress in the field of crystals unharmonicity and by the applications of these materials. In the course of our study the thermodymamical function of nonlinear anisotropic medium for adiabatic conditions of experiment has been used in the form: [image omitted] where ηIJ, χM are the components of the general tensor of deformation and of the electric field correspondingly. In equation (1) the terms conditioned by elastic (CIJKLQR), dielectric (ε NMP), piezoelectric (eNIJKL) nonlinearities and electrostriction (HMNIJ) have been taken into account.
