Abstract
Three series of films were obtained by magnetron sputtering of the composite C-Ni target with different ratios C/Ni (vol. %) = 60/40; 40/60; 30/70. The effect of the substrate temperature on the structure and the size of film-forming nickel nanocrystallites with a carbon shell was studied with using X-ray diffraction analysis. The cluster nature of film deposition on the growth surface was established by using atomic force microscopy. The saturation magnetization of nickel nanoparticles 4πMS was measured by the inductive-frequency method and the substrate temperature dependence was studied. It has been shown that the films with a high carbon content exhibit magnetism only when deposited on hot substrates. The films with the minimum carbon concentration exhibit ferromagnetic behavior even when deposited on a relatively cold substrate.
