The results of investigations (ferromagnetic resonance response and the non-resonance one) of n magnetic Co/Cu multilayers in frequency bands 20-80 GHz and 140 GHz are presented. It is shown that the magnetization saturation of the structure under study depends on the Cu-interlayers thickness. The high-frequency magnetoimpedance behavior in the structures under study at weak external magnetic field has been analyzed. Rather small magnetic hysteresis of transmission coefficient has been revealed. It is shown that the module of high-frequency impedance demonstrates the weak dependence on the frequency at millimeter wavelength band.
