Abstract

In this study, the effect of additions on magnetic properties in the system of [$Ni_{0.32}Zn_{0.68}$] 1-x Mx $Fe_2O_4$ have been investigated. The additions, Co or Mg or Cu, was added in turn in place of M, and its composition was varied from 0.1 mo1% to 0.5 mo1%. The materials were blended by hot petroleum drying method, and sintered with the rate of 30$0^{\circ}C$/h in the air. The sintering temperatures were varied from 110$0^{\circ}C$ to 130$0^{\circ}C$, with the intervals of 5$0^{\circ}C$, and matured for 3hrs. The results are: 1) The permeability decreased when the addition, MgO or CoO, was added, and it increased when CuO was added. 2) Resistivity had the lowest Value when CuO was added.
