Influence of oxygen and water vapor in the chamber during the deposition of thin-film nanocomposites (Co40Fe40B20)x(LiNbO3)100-x on the electrical properties of the heterogeneous system has been studied. A significant increase in the resistivity of (Co40Fe40B20)x(LiNbO3)100-x nanocomposites with an increase in the partial pressure of reactive gases (oxygen and water vapor) has been established. A significant shift of the percolation threshold towards higher metal phase concentration in the film plane and perpendicular to the film was found during the synthesis of composites with the addition of reactive gases, which is associated with an increase in the volume concentration of the dielectric phase. It is revealed that the percolation threshold when measured in the geometry perpendicular to the plane of the film corresponds to a significantly lower concentration of atoms of the Co40Fe40B20 alloy than in the case of measurements in the plane of the film, which is associated with the elongated shape of the metallic granules in the direction of film growth and the effects of Coulomb blockade suppression by a high transverse electric field.
