    Preparation and Magnetic Properties of Monodisperse Nanocomposite Hollow Spheres

    We present a simple process to prepare the hollow ceramic (CoFe2O4/SiO2) composite nanospheres and hollow alloy (Co33Fe67/SiO2) composite nanospheres. The hollow CoFe2O4/SiO2 composite nanospheres were prepared b...
