The structural, magnetic, and optical properties of Ni–Mg–Zn ferrite prepared with different complexing agents via sol–gel method

Different complexing agents were used to prepare Ni–Mg–Zn ferrite with the composition formula Ni0.2Mg0.2Zn0.6Fe2O4 via sol–gel method, which included citric acid, oxalic egg white, and EDTA. The without agent was also prepared as a comparison. chemical phases of samples analyzed by X-ray diffraction (XRD), indicated that had spinel phase structure. lattice constants are in range 8.3980–8.4089 Å. structure further studied Fourier transform infrared spectroscopy (FTIR). There two typical characteristic bands related stretching vibrations FTIR spectra. Scanning electron microscope (SEM) micrographs transmission (TEM) images showed particles have shape spherical cube. Energy dispersive spectrometer (EDS) elements ingredients samples, Ni, Mg, Zn, Fe, O. photoelectron (XPS) is examine elemental state sample EDTA agent. optical properties investigated photoluminescence spectra UV–Vis spectroscopy. Vibrating magnetometer (VSM) characterize magnetic properties, hysteresis loops revealed ferrimagnetism behavior samples.
