摘要：

Fe3O4 nanoparticles with tunable size and shape were synthesized by high-temperature organic solution method. The size and shape of nanoparticles can be tuned by varying the ratio of surfactant to precursor and refluxing temperature. Large surfactant : precursor ratio resulted in cubic shape, while small ratio brought out spherical shape. As-synthesized Fe3O4 nanoparticles had single crystalline structure and showed ferromagnetic at room temperature. Diamond shape nanoparticles exhibited coercivity as high as 440 Oe at room temperature. Room temperature ferromagnetic Fe3O4 nanoparticles have many technological applications including data storage, energy conversion, and nanomedicine.
