Abstract

Core/shell structured composites of hollow spherical CoFe₂O₄and CNTs were in situ synthesized using a CVD method with ethanol as a carbon source. CoFe₂O₄hollow spheres were used as cores, catalysts and magnetic ingredients simultaneously. It was found that the shell of CNTs uniformly grew on the surface of CoFe₂O₄hollow sphere cores. The reflection loss reached −32.8 dB at 11.7 GHz for the core/shell composites with a thickness of 2 mm.
