It is shown that as a result of irradiation by Ar ions, the surface of investigated materials is depleted with oxygen and is enriched with metallic components/ The substitutions of La atoms for Li atoms in La manganite and Ba atoms for Ca atoms in Sm-Ba manganite have been investigated by X-ray diffraction. The lattice symmetry of phases, which compose these materials, have been determined. The substitution limits in studied systems have been determined as well.
