| Abstract: | Fe3O4 nanorods were fabricated by hydrothermal method,using sodium citrate as additive. The as-prepared samples were characterized through XRD,SEM,TEM,HRTEM and ED. The formation mechanism of Fe3O4 nanorods was also discussed. The results indicate the as-prepared Fe3O4 nanorods with diameter of 50～80 nm and length of more than 2 μm. Fe3O4 nanorods have higher saturation magnetization and coercitivity of 77.8 A·m2·kg-1 and 39.6 kA·m-1,respectively. |
