Synthesis and Characterisation of Nickel Ferrite Nanoparticles Prepared by Spray Pyrolysis Method
Authors(3) :-Anila I, Subin P. John, Jacob Mathew M Nickel ferrite nanoparticles of ultrafine size were successfully prepared by spray pyrolysis method. The structural characterization of the samples is done using XRD and FTIR. XRD pattern of all samples show the formation of single phase cubic spinel structure.The distribution of cations among the two interstitial sites has been estimated by the Rietveld refinement of XRD pattern. The FTIR spectra show two strong absorption bands, confirm the presence of metal - oxygen complexes within the spinel lattice. The HRTEM micrographs demonstrates ultrafine particles having cubic morphology and the average particle size obtained is in good agreement with that estimated from XRD. The elemental analysis has been carried out using EDS, confirmed the purity of the synthesized sample. The room temperature magnetic properties of the sample were measured by using a VSM and revealed the soft magnetic nature of the sample and the same has been confirmed by room temperature Mossbauer studies. The cation distribution estimated from Mossbauer spectroscopy and Rietveld refinement confirm the mixed spinel structure of the spray pyrolysis synthesized Nickel ferrite nanoparticles.
