Effect of Sintering Temperature on Structural and Magnetic Properties of Ni0.6Zn0.4Fe2O4 Ferrite: Synthesized from Nanocrystalline Powders

The effect of sintering temperatures (Ts) on the structural and magnetic properties of Ni0.6Zn0.4Fe2O4 (NZFO) ferrites synthesized by conventional double sintering method has been reported. The samples are sintered at 1200, 1250 and 1300 °C. The X-ray diffraction (XRD) analysis reveals the formation of a single phase cubic spinel structure of the sample. The magnetic parameters such as saturation magnetization, Ms; coercive field, Hc; remanent magnetization, Mr and Bohr magneton, μB are determined and well compared with reported values. The obtained values are found to be 71.94 emu/gm and 1.2 Oe for Ms and Hc, respectively at Ts=1300 oC. Curie temperature (Tc) at various Ts has also been calculated. It is noteworthy to note that the sample with a very low Hc could be used in transformer core and inductor applications.
