摘　　要：Fe3O4/Au磁性纳米复合微粒由于具有一些奇异的物理特征而被广泛的应用于各个领域。因此,有关磁性纳米复合颗粒的制备已成为目前的一个研究热点。实验中用还原法制备了Fe3O4/Au纳米复合微粒,通过扫描电子显微镜对其表面形貌进行了观测,结果表明,制备的FeO/Au纳米复合微粒呈球形,颗粒间没有明显团聚,大小均匀,分散性好。Fe3O4/Au magnetic nanoparticles have the wide promising applications due to their unique physical properties. Therefore, the works related to the preparation of magnetic nanocompositions have become the present hot research. The Fe3O4/Au composite nanoparticles were synthesized by reduction in solution. The surface images of Fe3O4/Au composite nanoparticles were observed by scanning electron microscopy,and the results showed that the Fe3O4/Au composite nanoparticles were sphericity. The particles did not make any agglomeration. They showed outstanding monodisperse property.
