Abstract
AbstractCompositions having the general formula Ni1−xZnxFe2O4 with x = 0.30, 0.35, 0.40, 0.45 have been sintered at 1100, 1150, 1200, and 1240°C to attain different microstructures. The grain size D for a particular composition increases linearly with increasing sintering temperature. The lattice parameter α and magnetization Ms are seen to be invariant with the change in sintering temperature. The coercive force Hc and the remanent ratio R = Mr/Ms are seen to depend on the sintering temperature and hence on D. α and M, are found to increase with the increase of the Zn content, whereas Hc values show a decreasing trend with the Zn content. The compositional, thermal, and microstructural variation of hysteresis parameters like Ms, Hc, and R = Mr/Ms reveal that magnetic grains in the compositions investigated are of multi‐domain type. This result is supported by ac susceptibility data.
