摘　　要：随着纳米科技不断的发展,磁性材料也逐渐的进入了纳米材料的新纪元。由于纳米粒子具有小尺寸效应、表面效应、量子尺寸效应以及宏观量子隧道效应,导致了磁性纳米材料的磁学性能有了很大的变化,扩展了其应用前景。文章介绍了Fe3O4磁性纳米粒子的四种制备方法:共沉淀合成法,水热合成法,微乳合成法和微乳-凝胶合成法。Magnetic materials gradually entered the new era of nanomaterials with the development of nano technology. Because of the nanoparticles with small size effect, surface effect, quantum size effect and macroscopic quantum tunneling effect, the magnetic properties of magnetic nanomaterials have changed a lot, extended its application prospect. The paper introduces four kinds of preparation methods of magnetic Fe3O4 nanoparticles： coprecipitation synthesis, hydrothermal synthesis, microemulsion method and microemulsion-gel method.
