ABSTRACT
The effect of iron deficiency of Ni0.30+2xZn0.70 Fe2-2x O4-4x with X = 0.00, 0.01, 0.02, 0.03 and 0.04 system on their magnetic properties was carefully studied. X-Ray Diffraction analysis identified single-phase ferrite. It was found that sample with 0.47 mole fraction of iron oxide in the series of iron-deficit NiZn-ferrite was the most effective value for the formation of densed samples. Grain size of 31.8um and highest theoretical density, 0.78%, were obtained for the sample. On the other hand, sample with 0.48 mole fraction of iron oxide gave the highest experimental density (5.0905 gcm-3) and saturation induction (2757Gausss). It is speculated that cationic and anionic vacancies were sufficiently formed for the diffusive transportation of metal ions to occur with relative ease during sintering thus profoundly affecting the magnetic properties. The magnetic properties of some of the samples obtained are suitable as core materials for inductor.
