Maghemite and magnetite nanoparticles and nanorode are now losing interests in the field of nanobiotechnology and pharmaceutical for their applications. This paper reports on a hydrothermal process for the synthesis of Fe2 O3 in the γ-phases nanorodes, when the hydrothermal temperature was 100 ̊ C. The uniqueness of the method lies in the use of ferrous ammonium sulphate, hexamine was added as the stabilizer and hydrolyzing agents. The crystal structure, shape particle and magnetic properties of the samples were determined by X-ray diffraction (XRD) and Transmission electron microscopy (TEM) and magnetometer (AGFM), respectively. The particle size was 60nm and length in the range of 300nm. The magnetic behavior of the particles was like the typical behavior of superparamagnetic particles, so smaller particles can improve the magnetic properties and decreasing the coercivity.
