ABSTRACT

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 Co_0.8Zn_0.2Fe₂O₄ nanoparticles, highlighting their potential in semiconductor technology, nanosensors, biomedical applications, and more. 

Significance of the Study:
