Permeability spectra of Co2Z hexaferrite compacts produced via a modified aqueous co-precipitation technique

► Development of a modified aqueous synthesis method for Co2Z hexaferrites via single sintering. ► Characterization of the hexaferrites′ morphologic, magnetic, and electric properties. ► Investigation on the effect of magnetic orientation on the ferrites′ permeability. ► Effect of bias fields on μr has been presented towards antenna applications in L and S-bands.
