In the present study, the influence of Al and Ga admixture on the lattice parameters and the Curie point T_{C} of the La(Fe, Co, Si)_{13} compound was discussed. The measurements were carried out on ribbon samples of LaFe_{11.0}Co_{0.8}Si_{1.2}, LaFe_{11.0}Co_{0.8}(Si_{0.4}Al_{0.6})_{1.2} and LaFe_{11.0}Co_{0.8}Si_{1.1}Ga_{0.1} alloys. The samples were subjected to annealing in the inert gas atmosphere at 1323 K for 24 h. The change of lattice parameters a with admixture of Al and Ga was determined from the X-ray diffraction analysis. Furthermore, changes of the Curie point with the alloy composition were observed.
