Ni0.5Zn0.5Fe2O4 has been synthesized using mechanical alloying method with two variables (milling time and ball-to-powder weight ratio (BPR)) were varied in order to study its effect on the magnetic properties of the material. The effects of these two variables were studied using XRD, SEM, TEM and later by impedance analyzer with the frequency range from 1 MHz to 1.8 GHz. The results obtained however show that there are no significant trends to relate the milling time and BPR with the permeability and losses of the material studied. After being sintered at 1150 °C, all the effects of alloying process seem to diminish.
Research highlights► We studied the effects of BPR and milling time on permeability of Ni0.5Zn0.5Fe2O4. ► The effects were studied using XRD, SEM, TEM and impedance analyzer. ► No relationship between the milling time and BPR with the permeability and losses. ► The alloying effects are eliminated after sintering. ► The magnetic properties of these samples are influenced by the sintering process.
