Abstract: The cobalt-nickel coatings containing carbon were obtained by the chemical deposition method from salt solutions of transition metals using arabinogalaktan as a reducing agent. A crystalline structure and chemical composition of the coatings were detected. Carbon is found to be present in the form of graphite inclusions. Saturation magnetization, field of local anisotropy, and the size of correlation radius of axes of anisotropy were found by magnetic measurements for the coatings synthesized. The measurements carried out by ferromagnetic resonance allowed one to determinate the effective magnetization and the field of perpendicular anisotropy.

Keywords: chemical deposition, magnetic coating, ferromagnetic resonance, magnetization curve, magnetic anisotropy.
