  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 {\deg}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, {\mu}B 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.
