EFFECT OF ZN DOPANT ON PROPERTIES OF LI FERRITE SYNTHESIZED BY SOLUTION COMBUSTION METHOD

Abstract: Herein, Urea assisted solution combustion method has been used for the preparation of stoichiometrically pure and Zn doped Li ferrites. Urea acts as a capping agent and helps in the formation of nanostructures. Solution combustion method helps easier formation of ferrites in a single step, at relatively lower temperature and in shorter time than the reported methods. Powder X-ray diffraction (XRD) studies with diffractometer indicate high purity, single phase spinel ferrites formation. Magnetic studies by vibratory sample magnetometer (VSM) reveal an increase in the magnitude of saturation magnetization with increasing Zn content up to x = 0.3. The Zn doped Li ferrite formed possess high dc-resistivity values which make them suitable for high-frequency applications. Apart from the academic interest involved, these investigations are of technological importance in the view of the fact that their end products (ferrites) play a key role as electro-magnetic materials in the modern industry.
