Among the magnetic materials ferrites are of great interest due to its distinctive properties. Ferrites exhibit a spontaneous magnetic moment below a Curie temperature and act as insulators at low temperature. Sincethey have been used in number of technological applications like microwave devices, magnetic and magneto optic recording, data storage etc. The incredible magnetic, electric and dielectric properties of ferrites make them more attractive and applicable in the current field of science and technology. In the present study vanadium ferrite nanoparticles were synthesized by microwave assisted method. The structural properties of synthesized nanoparticles are carried out from X-ray diffraction technique. The presence of peaks confirms the crystalline nature of the vanadium ferrite nanoparticles. The crystal structure, crystalline size (D), Dislocation density (8) is determined from XRD data. Also using Williamson-Hall plot micro strain value is calculated.The different molecular vibrations are confirmed through Fourier Transformed Infrared Spectroscopy (FTIR) vibration spectra. From the Ultra Violet Spectroscopicdata using the Tauc relation, the energy gap (Eg) at the edge of absorbance band is calculated as 4.28eV for direct and 4.84 eV for indirect transition. The morphological studies are done through Scanning Electron Microscope (SEM). From the SEM micrographs we confirm the presence of spherical nanoparticles and they are arranged uniformly. From VSM analysis, we calculated the saturation magnetization as 20.00 emu, coercivity as 125.96 g, and retentivity is 130.45 emu.
