N2 - We report a simple technique for the preparation of lanthanum ferrite LaFeO3+d nanopowders by the polymerizable complex (PC) method based on the Pechini-type reaction route. A mixed solution of citric acid (CA) and ethylene glycol (EG) with La and Fe ions was polymerized. The formation mechanism, the homogeneity, and the structure of the obtained powders have been investigated by thermogravimetry, X-ray diffraction, Raman spectroscopy, and scanning electron microscopy (SEM) measurements. X-ray diffraction results indicated the formation of perovskite-type, which crystallizes in orthorhombic system LaFeO3+d when the La-Fe polymeric precursor was treated at 550 °C for 6 h.
