Substitution of Zinc Cation in Nickel Ferrite Synthesized by Sol-Gel Method and Evaluation of its Effect on Microwave Absorption, Structural and Magnetic Properties

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.
