Oriented magnetite (Fe3O4) nanorods have been successfully synthesized using a simple ethylenediamine-assisted hydrothermal technique. The samples were characterized by X-ray diffractometer, transmission electron microscopy, Fourier transform infrared and vibrating sample magnetometer. The cubic spinel structure Fe3O4 nanorods show a good crystalline state and the diameter is similar to 5 nm with lengths up to 0.5 mu m. Experimental results indicate that ethylenediamine plays a crucial role in determining morphological features. The Fe3O4 nanorods exhibit ferromagnetic behavior at room temperature with a magnetic saturation value of 72.94 emu g(-1). The growth mechanism based on the results of control experiments is also discussed.
