- Abstract
Using sol-gel measure to prepare CoFe2O4 nanoparticles, and then formed a Co3Fe7-Co magnetic metal nanoshell in the surfaces by H2 thermal reduction. The static and dynamic magnetism of the samples annealed in different temperature but reduced in the same conduction were investigated. The result shows that the saturation magnetization, imaginary part of complex permittivity and permeability, which correspond to the dielectric and magnetic loss, are intensely enhanced with reduction process. And this result in good microwave absorption properties for CoFe2O4/Co3Fe7-Co nano core/shell structure.
