Nano crystalline mixed ferrites can be prepared through different methods. In the present work a comparison was made on sol‐gel auto combustion method and co‐precipitation method by preparing Nickel Zinc Ferrite. The prepared samples were calcined at different temperatures and were characterized by powder XRD, FTIR. X‐ray diffraction analysis indicated the formation of ferrite in nanophase. The lattice parameter was found to be in the range 8.31–8.41Ao. This confirms that nano crystalline ferrite samples are in the cubic spinel structure. An average nano crystalline size was estimated from XRD by the Scherrer’s equation. FTIR study also confirms the formation of ferrites. Sol‐gel auto combustion technique was superior to co‐precipitation method for producing single phase nano particles with smaller crystallite size.
