  In this study were examined the effect of adding zinc cation instead nickel cation on the structural and magnetic properties of nickel ferrite prepared by sol-gel method. X-ray diffraction, field emission scanning electron microscopy, energy resolution spectroscopy, Fourier transform infrared spectroscopy, vibrating sample Magnetometer and vector analysis network device produced were used to verify the structural characteristics and magnetic ferrite particles. Single temperature recognized for nickel ferrite doped with zinc ions, 1200oC.For samples the doped ferrite phase and the second phase was achieved without any impurities. Scanning electron microscopy images showed obtained by particle size increases with increasing substitution of cation zinc. Breakdown spectroscopy graphs showed substituted increase energy and reduce peak of cation zinc peak size by increasing the nickel of cation. Fourier transform infrared charts compounds to confirm the results of X-ray diffraction patterns indicate the phase formation and placement of metal cations in spinel structure. Magnetic hysteresis curves, respectively increasing the saturation magnetization and the residual magnetization to combine x=0.6 and then reduce them to combine x=1. Waste dehydrogenation magnetic have consistently decreasing trend until combined x=0.8 and then will combined x=1. With zinc substitution increased reflection loss. Zinc cation by nickel ones, causes improving of the magnetic properties and microwave absorbtion and this material could be used for the different applications such as microwave absorbance.

  In this study cadmium doped nickel copper ferrite Ni0.5Cu0.5Fe2O4 (cd doped) nanoparticles with spinel structure were synthesized using co-precipitation method. The nanoparticles were employed as a gas sensing material. X-ray diffraction (XRD), X-ray fluorescence (XRF) and transmission electron microscopy (TEM) techniques were used to characterize the nanoparticles structure. The sensing behavior of the nanoparticles was examined in the presence of different gases including. Acetone, acetonitrile, acrylonitrile, formamide, caron tetrachloride, vinyl acetate, ethanol, ammonia, and methanol. The characterization process was performed for a concentration of a 200 ppm and within a temperature interval from 50 ˚C to 300 ˚C and the best sensing behavior was found to be at 200 ˚C. Furthermore, various concentrations of acetonitrile gas at 200 ˚C within a concentration interval of 20 to 200 ppm were tested and it is found that the higher concentrations will result in a better response.
