Production of Magnetic Nanoparticle-Based Ferrites and Comprehensive Characterization of Their Electrical and Magnetic Properties in Colloidal Systems

This study investigates the synthesis, structural characterization, and physicochemical properties of magnetic nanoparticles derived from iron group metals (Fe, Co, Ni) and their corresponding ferrite dispersions. Magnetic nanoparticles were synthesized via chemical condensation, and their morphology and structure were analyzed using transmission electron microscopy (TEM) and X-ray diffraction (XRD). The synthesized magnetic nanoparticles, comprising Fe3O4, CoFe2O4, and NiFe2O4 ferrites, exhibited nano-scale dimensions ranging from 10 to 50 nm. The precise correlation between TEM and XRD measurements validated the structural and dimensional characteristics of the synthesized nanoparticles. Aqueous-based magnetic liquids with varying nanoparticle concentrations were prepared, enabling systematic investigation of their electrical conductivity and magnetic susceptibility at ambient temperature. The experimental findings provide critical insights into the fundamental properties of magnetic nanoparticle-based colloidal systems, potentially facilitating advanced applications in materials science, magnetic device engineering, and emerging technological domains. The methodological approach and results presented herein contribute to the expanding understanding of magnetic fluid behavior and performance.
