Abstract
The electromagnetic parameters of synthesized M-type hexagonal ferrite, Ba0.5Sr0.5CoxTixFe( 12-2x)O19 (x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0), are measured from 8.2-12.4 GHz. The substitution of Co2+ and Ti4+ ions increases dielectric loss in the ferrite, suggesting for EMI shielding applications. The preferential site occupancy of substituted ions changes resistivity of ferrite. The various mechanisms behind variations of investigated parameters are discussed in this paper.
