    Synthesis and characterization of metal ferrites and study of their magnetic properties in polymer thin films
    (University of Management and Technology, 2015) Abdul Sattar
    Nanoparticles of Nickel ferrites have been prepared using the modified co-precipitation technique; the methodology involved the controlled mixing of Nickel chloride 0.2M solution and Ferric chloride 0.4M solution in the ratio of 1:2 respectively. The precipitates were dried at 105oC for 24h, annealed at 600oC for one hour and characterized using SEM and XRD techniques. The SEM and XRD results showed that prepared particles were in nano range. Prepared material having good surface morphology was incorporated into starch grafted methylmeth acrylate copolymer by in-situ polymerization method. The nano composite prepared in this way was characterized by SEM, FTIR and VSM for the magnetic properties. The results of these techniques proved the usefulness of the material as biodegradable thin films having controllable magnetic properties for potential use as magnetic strips.
