The results of obtaining and X-ray diffractometric studies of the structure of multilayer heterostructures of barium-strontium titanate and lanthanum manganite on monocrystalline magnesium oxide substrates with different orientation of crystallites in layers relative to the substrate plane are presented. To create multilayer film structures, the method of high-frequency cathode sputtering of ceramic targets Ba0,8Sr0,2TiO3 and LaMnO3 was used at high pressures of oxygen working gas (~1 Torr). Depending on the growth conditions and the sequence of the layers Ba0,8Sr0,2TiO3 and LaMnO3, monocrystalline or polycrystalline films can be obtained. When used as the first layer of LaMnO3, LaMnO3 and Ba0,8Sr0,2TiO3 films are polycrystalline with a pronounced texture (001) and (011). For a multilayer heterostructure with the first layer Ba0,8Sr0,2TiO3, Ba0,8Sr0,2TiO3 and LaMnO3 films are epitaxial, the crystallographic axes of which are oriented parallel to the crystallographic axes of the substrate. The disorientations of the crystallographic axes does not exceed 0.7°. Compressive stresses are present in all layers of multilayer film structures in the substrate plane.
