Abstract: CoFe2O4/SiO2 nano-composites were prepared via the sol-gel method. Structure, grain size and magnetic properties of CoFe2O4/SiO2 nano-composites were investigated by X-ray diffraction (XRD) and vibrating sample magnetometer (VSM). The results show that with the increase of the content of SiO2, the grain size, the saturation magnetization and coercivity of samples decrease. 

Key words: nano-composite, CoFe2O4/SiO2, structure, magnestism
