Surface modification of the ball-mill prepared Fe3O4/C magnetic composites was carried out using a precipitation method. Fe/C magnetic composites were obtained by solid-state high-temperature deoxidating of the modified Fe3O4/C magnetic composites. The obtained products were characterized by transmission electron micrograph (TEM) images, X-ray diffraction (XRD) pattern, thermogravimetric analysis (TG) and grain-size distribution. The thermal stability of the drug targeting magnetic composites and the change of the magnetic properties of the composites in air and similar human inner environment were also measured. The results reveal that the properties of the prepared products can satisfy the requests of practical applications.
