Dependence of magnetic properties and microstructure of mechanically alloyed Ni0.5Zn0.5Fe2O4 on soaking time

► Ni0.5Zn0.5Fe2O4 samples sintered at relatively low temperature (800 °C). ► The degree of crystallinity depends on the soaking time. ► Correlation between morphology, phase analysis, permeability and hysteresis loops. ► Increase in crystalline-growth formed a mixed of super- and ferro-magnetic grains.
