The preparation of NiZn ferrites with varying composition have been synthesized by mechanical milling method. The starting iron oxide (Fe 2 O 3 ), nickel oxide (NiO), and zinc oxide (ZnO) were mixed with seven compositions of Ni 1-x Zn x Fe 2 O 4 with x = 0.1 – 0.7. The effects of the composition on the structural and magnetic properties of the ferrite have been investigated. Structural properties were observed by X-ray diffraction (XRD) (Bruker’s). XRD patterns match well with the characteristic reflections of f d-3 cubic spinel structure, and it confirms that the all samples have single phase. Magnetic properties characterized by Permagraph Magnet Physik at room temperature. Hysteresis curve results show that varying composition influence the magnetic properties. Sample that have the highest Ms and Mr values is when x = 0.3 with magnetization of remanence (Mr) = 30.1538 emu/g, magnetization of saturation (Ms) = 39.1642 emu/g, coercivity (HcJ) = 0.3040 kA/m, and density = 4.40 g/cm3. The highest HcJ value when x = 0.2, coercivity (HcJ) = 0.4050 k/m.
