Abstract
The frequency dependences of the magnetic permeability of Ba 3 Co 2 Fe 24 O 41 ferrite with hexagonal crystalline structure are given which have been obtained by waveguide and resonator methods in the frequency range 0.1–11 GHz. The data on the magnetic spectra of this material available in the literature have been analyzed to select the most reliable experimental results. The expert judgement on the spectra was made using the Cramers-Kronig dispersion relations. It has been shown that the Cramers-Kronig relations can be used to correct complex magnetic permeability measurements by reciprocal recalculation of the frequency dependences of the real and imaginary parts.
