Microstructure and Magnetic Studies of Zinc Ferrite Nano-Particles

摘要

Zinc ferrite nano-particles are synthesised by advanced combustion route. The nano-sized Zn ferritecharacterized by X-ray diffraction (XRD), Scanning electron micrographs (SEM) and Energydispersive X-ray (EDX) techniques. The magnetic properties were determined by using vibratingsample magnetometer (VSM). The preparation method investigated brought about formation ofmoderate crystalline ZnFe2O4 as a single phase with irregular shape. Both the saturation magnetization(60 emu/g) and the remnant magnetization (20 emu/g) were found to be highly depending upon thesize and crystallinity of the investigated ferrite. Our results indicate that this method might provide apromising option for synthesizing high-quality nano-sized ZnFe2O4.
