Abstract (Fe, Ni)4N--coated (Fe, Ni) nanoparticles were synthesized by the thermal ammonolysis reaction in a NH3 atmosphere at 400℃ and 450℃ using (Fe, Ni) nanoparticles as the precursor. 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.
