【 摘 要 】

The frequency dependences of the magnetic permeability of textured composite based on Ba3Co2,4Fe23,2O41ferrite are given. The magnetic permeability spectra were obtained by coaxial method in the frequency range 0.01-18 GHz. The expert judgement on the spectra was made by using Cramers - Kronig relations. It was shown, that the Cramers - Kronig relations can be used to correct magnetic permeability measurements by reciprocal recalculation of the frequency dependences of the real and imaginary parts.
