Modified structural properties of nickel content in Ni x Co 1-x Fe 2 O 4 with x = 0,0.2 and x = 0.4 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 parameters change with the enhancement of the Ni-concentration. The FTIR spectrum showed two prominent absorption bands i.e. at around k of 400 cm −1 and 600 cm −1 , where metals at tetrahedral and octahedral sites reflect intrinsic vibrations, respectively. Finally, the decrease of saturated magnetization M S from 77.3 emu/g to 33.9 emu/g replacement of Co 2+ cation with Ni 2+ .
