Abstract:	The synthesis conditions for single-phase solid solutions based on lanthanum gallate, LaGa_{1 ? x}Mg_xO_{3 ? δ}(x= 0–0.25, solid-phase method) and La_{1 ? y}Sr_yGa_{1 ? y}Mg_yO_{3 ? δ}(y= 0–0.2, glycine nitrate method), have been investigated. The structural parameters have been calculated using X-ray powder diffraction data. The IR and Raman spectra have been analyzed. Regularities in the changes in the structural parameters and vibrational spectra with composition are established.
