中文摘要	Magnetic and electromagnetic wave absorption properties of alpha-Fe(N) nanoparticles, synthesized by chemical vapor condensation and then kept in air for 5 years, have been studied. The magnetic properties of the alpha-Fe(N) nanoparticles were slightly decreased because of the degradation in air. A slight increase in the thickness of oxide shells results in an excellent dielectric loss. The alpha-Fe(N) nanoparticles exhibited outstanding reflection loss (RL < -20dB) in a 4.5-18 GHz for the absorber thicknesses of similar to 1-3.1 mm, and an optimal RL of -37.5 dB was obtained at 10.4 GHz with an absorber thickness of 1.6 mm. The broadest bandwidth (RL < -10 dB) from 13.3 to 17.4 GHz, covering almost the whole Ku-band, is obtained for a 1.2 mm layer. (C) 2009 Elsevier B.V. All rights reserved.
