Abstract
Iron-tungsten oxide nanospinel have been prepared by two methods: microwave combustion method and Pechini method. The W-Fe bimetallic ferberite was successfully synthesized by microwave-assisted techniques. The resultant magnetic nanocomposites were characterized by thermal analysis, X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, energy-dispersive X-ray, transmission electron microscopy, nitrogen adsorption, and magnetic properties measurement system. The prepared ferberite nanoparticles (50–65 nm) using microwave combustion method were pure monoclinic ferberite. The ferberite nanoparticles showed ferrimagnetic hysteresis loop with values of saturation magnetization and coercivity of 4.829 A.m2/Kg and 0.0312 T, successively.
