The results of experimental studies of magneto-optical (MO) and magnetic resonance (MR) properties of nanogranular film structures (CoFeB)x(SiO2)100-x and (CoFeB)xС100-x obtained by the ion-beam sputtering method are presented. Magnetic spectra were registered by the method of ferromagnetic resonance (FMR), and magneto-optical spectra were registered by observation of Transversal Kerr Effect (TKE). A comparative analysis of the experimental MO spectra and FMR spectra for systems (CoFeB)x(SiO2)100-x and (CoFeB)xС100-x indicates that a multi-phase structure realizes in the (CoFeB)xС100-x system. The existence of a multiphase structure is associated with possible plasma-chemical processes that can occur during the synthesis of nanosystems with carbon.
