| 中文摘要 | FeCo nanocapsules with FeCo alloy as core and amorphous Al(2)O(3) as shell have been synthesized by a modified arc-discharge technique. Three-dimensional coral-like aggregates are self-assembled by the nanocapsules in the arc-discharge process. The FeCo nanocapsules are ferromagnetic at room temperature. The electromagnetic-wave absorption properties of FeCo nanocapsules were investigated in the frequency range from 2 to 18 GHz. A reflection loss exceeding -20 dB was obtained in the frequency range of 5.2-15.9 GHz for absorber thicknesses of 2-4 mm. An optimal reflection loss of -44.8 dB was reached at 12.8 GHz for an absorber thickness of 3 mm. As a result, these FeCo nanocapsules may be applied in high-frequency electromagnetic-wave absorption. (C) 2008 American Institute of Physics. [DOI: 10.1063/1.2982411] |
