Abstract

The synthesis of Fe/TiO2 nanocomposite soft magnetic materials, incorporating Cu, Fe2O3, and Cu/Fe2O3;, was achieved using the mechanical alloying technique. Advanced characterization methods, including Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), X-ray Diffraction (XRD), and Vibrating Sample Magnetometer (VSM), were employed for a comprehensive investigation of structural, morphological, and magnetic properties of the nanocomposite at different synthesis stages. The crystallite size reaches its minimum value, while the lattice strain (ε) attains its maximum value in the FeCu/TiO2 nanocomposite, measuring 26.85 nm and 0.35%, respectively. Coercivity, magnetic remanence, and squareness ratio of Fe/TiO2 showed an upward trend with increasing milling time, reaching peak values after 5 h of milling. The FeTiO2 nanocomposite achieved maximum values for coercivity, magnetic remanence, and saturation magnetization. Notably, the squareness ratio demonstrated notable values for both FeTiO2 and FeCuTiO2.
