Recently, there has been an immense interest in the fabrication of composite nanoparticles, such as core-shell structural materials [1-6]. These core-shell composite particles may show special properties different from those of the core or shell particles. Thus, Au or Ag nanoparticcles were coated by silica. The silica shell not only stabilizes the colloidal Au nanoparticles, but also influences their optical property [3,6]. Furthermore, Halas et al. [5] have demonstrated that by varying the ratio of gold-shell to silica-core, the plasmon optical resonance of the Au shell and silica core strongly shifts across the visible spectrum and into the infrared region. Core-shell particles can be used as building blocks for different devices including tunable Photonic-Band-Gap (PBG) structures. Herein, we report on the fabrication of such particles with emphasis on the preparation of the Au nano-shells coated polystyrene (PS) with a diameter of about 700 nm.

Magnetic properties of the sets of Fe3O4(core)/CoFe2O4(shell) composite nanoparticles with a core diameter of about 6.3 nm and various shell thicknesses (0, 1.0, and 2.5 nm), as well as the mixtures of Fe3O4 and CoFe2O4 nanoparticles taken in the ratios corresponding to the core/shell material contents in the former case, have been studied. The results of magnetic research showed that the coating of magnetic nanoparticles with a shell gives rise to the appearance of two simultaneous effects: the modification of the core/shell interface parameters and the parameter change in both the nanoparticle’s core and shell themselves. As a result, the core/shell particles acquire new characteristics that are inherent neither to Fe3O4 nor to CoFe2O4. The obtained results open the way to the optimization and adaptation of the parameters of the core/shell spinel-ferrite-based nanoparticles for their application in various technological and biomedical domains.
