摘要	FCC-Co/Al(2)O(3) and FCC-Co/Y(2)O(3) nanocapsules were prepared by a modified arc-discharge technique, which exhibited the maximum magnetic resonance (mu") peak at the same frequency of 6.4 GHz. For the FCC-Co/Al(2)O(3) nanocapsules, the reflection loss being less than -20 dB was obtained in the frequency range of 9.6-11 GHz with an absorber thickness of 4-5 mm, while a minimum reflection loss of -29.7 dB was achieved at 10 GHz with an absorber thickness of 5 mm. The FCC-Co/Y(2)O(3) nanocapsules are with broader frequency range (9.7-12.4 GHz) and thinner matching thickness (2-4 mm) for RL < -20 dB, due to comparatively higher magnetization. The FCC-Co/Al(2)O(3) and FCC-Co/Y(2)O(3) nanocapsules may become attractive candidates for a new type of electromagnetic wave absorptive materials. (C) 2008 Elsevier Ltd. All rights reserved.
