- Abstract
α- FeO nanoparticles have been synthesized by gel evaporation method in air at 300°C. The average size of as synthesized α-FeO nanoparticle was estimated to be 30 nm and the particles were of good crystalline nature. Shape of the nanoparticles were slightly deviated from spherical which is attributed to the asymmetric growth of primary nuclei. MicroRaman and X-ray diffraction results have shown mixed phases of α-FeO and γ-FeO. However, the α-FeO phase is more predominant than γ-FeO due to the incomplete nucleation of α-FeO particles at the size of 30 nm. The vibrating sample magnetometer measurement shows that the nanoparticles possess ferromagnetic property.
