Facile Fabrication of Single Crystalline Fe₃O₄ Nanorods and its Magnetic Properties

Abstract:

Single crystalline Fe₃O₄ nanorods were fabricated in high yield via a facile hydrothermal route in the presence of sodium citrate as addition agent. The phase structures, morphologies, and sizes of as-prepared products were investigated in detail by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM). The diameter of magnetite nanorods is about 50~80 nm and its length is more than 2 μm. Room-temperature magnetic measurements showed that Fe₃O₄ nanorods exhibited high saturation magnetization and coercitivity of 77.8 emu/g and 98 Oe, respectively, while the as-obtained nanoparticles had low coercitivity value.
