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-<span style=\"color:red\">Co</span>/<span style=\"color:red\">Al</span>(2)O(<span style=\"color:red\">3</span>) 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-<span style=\"color:red\">Co</span>/Y(2)O(<span style=\"color:red\">3</span>) 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-<span style=\"color:red\">Co</span>/<span style=\"color:red\">Al</span>(2)O(<span style=\"color:red\">3</span>) and FCC-<span style=\"color:red\">Co</span>/Y(2)O(<span style=\"color:red\">3</span>) nanocapsules may become attractive candidates for a new type of electromagnetic wave absorptive materials.
