Description
Summary:— Nanoparticles of spinel ferrites with composition MFe 2 O 4 (M = Zn, Ni) have been effectively synthesized by hydrothermal and sol-gel routes, in which Triton-X 100 is used as a surfactant. The structure of ferrite nanoparticles has been characterized by X-ray diffraction, which has showed single cubic spinel phases for all the samples. The surface morphology and elemental composition have been examined by field emission-scanning electron microscopy (FE-SEM) and energy dispersive X-ray (EDX) spectroscopy. A combined morphology in shape of sphere, octagon, and agglomerated flakes were found on FESEM images for the nanoparticles synthesized by both methods. FTIR showed underlying absorption bands pertinent to the stretching vibration of metal at the octahedral and tetrahedral sites. Vibrating sample magnetometer (VSM) results showed saturation magnetization ( M s ) and remanence ( M r ) for spinels prepared by hydrothermal route to be more than those produced by sol-gel methods. The optical band gap values were estimated by diffuse UV-visible reflectance spectroscopy (DRS).
