The graphene/(1-x)BaFe12O19/CaFe2O4/xCoFe(2)O(4) ferrite composite powders were successfully synthesized by a deoxidation technique. The phase composition, morphology and electromagnetic properties of the composites were characterized by various instruments. The experimental results show that the graphene/(1-x)BaFe12O19/CaFe2O4/xCoFe(2)O(4) ferrite composites exhibit evidently enhanced microwave absorbing performance in comparison with the graphene/(1-x)BaFe12O19/CaFe2O4 and graphene/CoFe2O4 composites and the minimum reflection loss is -36.8 dB at 9.9 GHz with a thickness of 2.9 mm.
