The phase structure, composition, morphology, and the magnetic properties of the composite nanoparticles were examined by XRD, TEM and VSM. By dispersing the nanoparticles homogeneously into a paraffin matrix, the electromagnetic parameters of the nanoparticles were investigated in the frequency range of 2--18 GHz. The result show that the composite nanoparticles were (Fe, Ni) which were coated by (Fe, Ni)4N. Compared to precursor nanoparticles, the composite particles after nitriding had a larger complex permittivity due to multi-dielectric polarization, while the complex permeability exhibited a similar change tendency and a natural resonance peak at 7.8 GHz. It is calculated that the excellent microwave absorption (R<-10 dB)was obtained in the frequency range of 3.6--7.8 GHz and 2.0--6.4 GHz band, and that the minimum reflection loss were -53.5 dB and -34.5 dB at 3.2 GHz and 4.8 GHz for the composite particles at the nitriding temperatures of 400℃ and 450℃, respectively. It may be used as a radar absorption material at low frequencies.
