The impact of Cu, Ni and Fe<sub>2</sub>O<sub>3</sub> on the magnetic behavior and structural properties of FeSiO<sub>2</sub> nanocomposite synthesized through ball milling
Abstract
<jats:title>Abstract</jats:title><jats:p>The nanocomposite Fe-A/SiO<jats:sub>2</jats:sub> soft magnetic materials, with Cu, Ni, and Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> as dopants, were produced using a mechanical alloying technique. Our central objective was to explore the impact of process parameters on Fe/SiO<jats:sub>2</jats:sub> nanocomposite properties. We assessed varying milling time and dopant addition rates, analyzing structural, morphological, and magnetic aspects through SEM, EDS, XRD, and VSM at different synthesis stages. The XRD pattern revealed iron, Fe(Ni), Fe(Cu), and Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> with an average crystallite size of 28–39 nm and lattice strain of 0.0097%–0.0222%. Notably, the lattice parameters decreased from 0.2852 to 0.2836 nm. Among nanocomposites, FeCu/SiO<jats:sub>2</jats:sub> displayed the smallest crystallite size (34.3 nm), while FeNiSiO<jats:sub>2</jats:sub> showed the highest lattice parameter (0.2853 nm). The ATR analysis unveiled Si–O–Si stretching vibrations at 1052 cm<jats:sup>−1</jats:sup>, intensifying with milling time. The inclusion of Cu and Ni in the FeSiO<jats:sub>2</jats:sub> system significantly influenced the Si–O–Si bond. Coercivity and remanence magnetization in Fe/SiO2 increased notably with milling time, reaching 68.47 Oe and 8.73 emu g<jats:sup>−1</jats:sup>, respectively. The Fe/Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>/SiO<jats:sub>2</jats:sub> and FeSiO<jats:sub>2</jats:sub> nanocomposites exhibited the maximum values of coercivity (47.07 Oe) and remanence magnetization (12.24 emu g<jats:sup>−1</jats:sup>). Remarkably, the Fe/SiO<jats:sub>2</jats:sub> nanocomposite displayed the highest saturation magnetization, measuring an impressive 176.07 emu g<jats:sup>−1</jats:sup> after 30 h of milling, while FeCu/SiO<jats:sub>2</jats:sub> reached 165.64 emu g<jats:sup>−1</jats:sup> after 20 h. Overall, our findings suggest the Fe/SiO<jats:sub>2</jats:sub> nanocomposite as a promising high-frequency soft magnetic material.</jats:p>
