Abstract

The core/shell type of cobalt ferrite nanocluster formed on the surface of the ionic copolymer microsphere was prepared by in-situ co-precipitation method. The low treatment temperature at 90°C with an external magnetic field (0.5T) was used instead of the traditional high temperature annealing procedure. Interestingly, the crystalline structure and saturation magnetization of cobalt ferrite nanoclusters preparing with extra magnetic field are better than that of no extra magnetic field from the XRD and VSM verification. Furthermore, the hollow sphere type of magnetic particle can be obtained when the ionic copolymer is extracted from the core/shell nanocomposite by using tetrahydrofuran solvent with supersonic oscillation.
