Analysis and reoperation of the magnetic permeability spectra of textured composite based on Z-type hexaferrite by using Cramers-Kronig relations

摘要

The frequency dependences of the magnetic permeability of textured composite based on Ba3Co_(2,4)Fe_(23,2)O_(41) ferrite 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.
