Vlokh of Ministry of Education and Science of Ukraine popup.description2 The influence of nonuniform electrical and temperature fields on refringent and gyrotropic properties of crystals. In particular: 1) the dependence of induced optical activity for LiNbO3 crystals on the electrical field value was obtained, one of the electrogyration tensor components was determined (g41=(3,39±1,3)10(-12) m/V), the diffraction efficience at diffusion on photorefractive electrogyration grating was calculated (1,5%); 2) one of the gradient thermooptical effect's tensor components was determined (r22=(4.85± 0.43)10(-12) m/K) for LiNbO3 crystals; 3) manifestation of gradient piroelectrical effect was first detected.
