Abstract
The Fe3O4@SiO2 core-shell nanoparticles (NPs) had been successfully fabricated via direct decomposition of tetraethyl orthosilicate (TEOS) in solution under the presence of as-synthesized Fe3O4 NPs prepared by chemical coprecipitation method. The structure and magnetic properties of Fe3O4@SiO2 NPs were characterized and the result indicated that Fe3O4@SiO2 NPs are about 12Â nm in size with paramagnetic property. The possible growth and magnetic mechanism was discussed in detail.
