Comparison of nickel Ni 0.6 Co 0.4 Fe 2 O 4 and NiFe 2 O 4 were studied. The co-precipitation method was performed for the whole sample. After annealing of 600°C for 4 hours, the nanoparticles samples evaluated their structural properties by using Fourier Transform Infra-Red (FTIR) and X-Ray Diffraction (XRD). The XRD pattern confirms that the whole samples have the crystalline structure of the face-centered cubic (fcc) inverse spinel. Furthermore, the lattice and crystallite size of NiFe 2 O 4 increased when added Co 2+ . The FTIR spectrum showed two prominent absorption bands, i.e., at around k of 358 cm -1 and 588 cm -1 , where metals at tetrahedral and octahedral sites reflect intrinsic vibrations, respectively. Finally, the decrease of saturated magnetization M S from 22.2 emu/g and 9.92 emu/g replacement of Co 2+ cation with Ni 2+ .
