• Nanorods of Fe–TiO2 were synthesized at 100°C and room pressure by mixing titanium oxide wet gel TiO2·xH2O with a boiling solution of iron nitrate. The results of EDAX, performed on different selected area of the sample, revealed a homogeneous composition of about 3at% Fe. Electron diffraction and XRD measurements show that the as-prepared Fe–TiO2 and annealed one at 550°C have both a single rutile structure with no indication about the presence of a secondary phase. The transmission electron microscopy (TEM) micrographs show that both as-prepared Fe–TiO2 and annealed one at 550°C have nanorod-shape with dimensions length by diameter of about 60×5nm and 52×12nm, respectively. Magnetization measurements show that both samples present a nonzero remanence and a coercivity of 108 and 120Oe, respectively. At higher temperature, 850°C, Fe–TiO2 decomposes to rutile TiO2 and new iron–titanate phase.
