In this study, cadmium and chromium doped cobalt ferrite nanoparticles (Co1-xCdxFe2-xCrxO4) (x = 0, 0.1, 0.2, 0.3, 0.4, 0.5) were synthesized by hydrothermal method. Then, using X-ray diffraction (XRD), scanning electron microscopy (FESEM), Fourier transforms infrared (FTIR) and Raman spectroscopy, structural properties were investigated. XRD analyses show a single-phase spinel structure for annealed samples at 700 °C. The crystallite sizes decrease slightly by increasing Cd and Cr doping from 58 to 53 nm, in agreement with FESEM micrographs. The lattice parameter value was between 8.396 and 8.514 Å. The Raman spectroscopy analysis showed that Co1-xCdxFe2-xCrxO4 nanoparticles have a mixed spinel structure. Then, by using the vibrating sample magnetometer (VSM), we obtained the magnetic parameters of the samples. The maximum saturation magnetization of 76 emu/g and the maximum coercivity field of 1.125 KOe were obtained in the samples of x = 0 and x = 0.1, respectively.
