摘要	Electromagnetic (EM) characteristics of superparamagnetic graphite-coated FeNi(3) nanocapsules were studied at 2-18 GHz. Compared with FeNi(3) nanoparticles coated by an amorphous oxide layer, the natural resonance and attenuation properties of the graphite-coated FeNi(3) nanocapsules were dramatically enhanced, due to the coating of the graphite. Graphite layers can restrain the growth of FeNi(3) nanocapsules, increase the resistivity, enhance the resonance frequency, keep the real part of permeability almost constant at high frequency and increase the magnetic loss. As a result of enhanced natural resonance and attenuation properties, the FeNi(3)/C nanocapsules exhibit good EM absorption properties.
