Abstract The effect of sintering temperatures ( T s ) on the structural and magnetic properties of Ni 0.6 Zn 0.4 Fe 2 O 4 (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, M s ; coercive field, H c ; remanent magnetization, M r and Bohr magneton, µ B are determined and compared with reported values. The obtained values are found to be 71.94 emu/gm and 1.2 Oe for M s and H c , respectively at T s = 1300°C sample. Curie temperature ( T c ) for various T s has also been calculated. It is noteworthy that the sample with a very low H c could be used in transformer core and inductor applications.
