Novel cross α-Fe2O3 nanorods were obtained by forced hydrolysis of ferric chloride in the water solution system. The as-obtained products were characterised by X-ray diffraction (XRD), transmission electron microscopy (TEM), Raman spectrum, Brunauer-Emmett-Teller and vibrating sample magnetometry. XRD results revealed that the product exhibited α-Fe2O3 phase. A comprehensive TEM analysis revealed that the cross structures consisted of α-Fe2O3 nanorods with an average length of 400 nm and diameter of about 75 nm. Magnetic hysteresis measurement reveals that the novel cross α-Fe2O3 nanorods display weak ferromagnetic behaviour with a remanence of 0.115 emu/g and a coercivity of 491.5 Oe at room temperature.
