The real and imaginary parts of effective permeability tensor components of the nanostructured gyromagnetic medium based on a 3D periodic array of ferromagnetic (iron) nanospheres were calculated depending on the bias magnetic field at frequency f = 9,375 GHz. The comparison of the calculated frequency and width of line of ferromagnetic resonance in the nanostructured medium based on the magnetic nanoarray (the magnetic nanomaterial) and ones in the continuum gyromagnetic medium was done.
