Spinel ferrites (MeFe₂O₄) with divalent cations like Co²⁺ and Zn²⁺ exhibit unique crystal structures and magnetic properties, making them essential in various applications. This study focuses on CoZnFe-oxide nanoparticles (NPs), synthesized using a wet chemical method. X-ray diffraction (XRD) confirmed a single-phase cubic spinel structure, while scanning electron microscopy (SEM) revealed clustered, spherical nanoparticles with rough surfaces. Fourier-transform infrared (FTIR) spectroscopy identified absorption peaks corresponding to metal-oxygen bond vibrations. DC resistivity measurements indicated thermally activated conduction behavior, typical of semiconductors. Magnetic analysis through an M-H plot confirmed ferromagnetic behavior with significant saturation magnetization, coercivity, and remanence. These findings demonstrate the structural, electrical, and magnetic characteristics of Co0.8Zn0.2Fe2O4 nanoparticles, highlighting their potential in semiconductor technology, nanosensors, biomedical applications, and more.
