Processing and Investigation of Cd0.5Zn0.5Fe2-xCrxO4 (0 & LE; x & LE; 2) Spinel Nanoparticles

This study presents the synthesis of Cd0.5Zn0.5Fe2-xCrxO4 nanoparticles via the sol-gel method, along with a comprehensive characterization of their morphological, structural, infrared, and magnetic properties. The X-ray diffraction pattern confirms the formation of the spinel structure, and the cation distribution is estimated using X-ray analysis and confirmed by magnetization measurements. The crystalline size, ranging from 152 to 189 nm, and lattice parameter, varying from 8.51134 & ANGS; to 8.42067 & ANGS;, decrease with increasing Cr content. The saturation magnetization decreases from 55 emu/g to 10.8 emu/g, while the remanent magnetization increases (3.5 emu/g & LE; M-r & LE; 6.27 emu/g), and the coercivity increases (82 Oe & LE; H-C & LE; 422.15 Oe) with the addition of Cr ions. Fourier transform infrared (FTIR) spectroscopy reveals two absorption bands at & nu;(1) and & nu;(2), located near 600 and 400 cm(-1), respectively, which correspond to the vibrations of the metal-oxygen bonds in the spinel structure.

Automated summary

This study synthesizes Cd0.5Zn0.5Fe2-xCrxO4 nanoparticles using the sol-gel method and characterizes their morphological, structural, infrared, and magnetic properties comprehensively. The formation of the spinel structure is confirmed by X-ray diffraction, and cation distribution is estimated through X-ray analysis and magnetization measurements. The size and lattice parameter of the nanoparticles decrease with increasing Cr content, while saturation magnetization decreases, remanent magnetization increases, and coercivity increases as Cr ions are added. Fourier transform infrared (FTIR) spectroscopy shows absorption bands corresponding to metal-oxygen bonds in the spinel structure.
