Аннотация
Changes in the electroluminescence intensity and kinetics are recorded in lead magnesium niobate crystals excited by a sinusoidal electric field and the synchronous action of uniaxial mechanical stresses in the frequency range of inelastic mechanical relaxation. The results are of interest for the development of optoelectronic tensometry and new lines of research on relaxor ferroelectrics.
