Magnetic Behavior and Structural Properties of Fe10Al40(ZnO)50 and Fe10Al50(ZnO)40 Nanocomposites

Abstract

Nanocomposite materials comprising Fe10Al40(ZnO)50 and Fe10Al50(ZnO)40 were synthesized using the powder metallurgy technique. The investigation of their structural, morphological, and magnetic properties at various synthesis stages was carried out utilizing advanced characterization methods, including Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), X-ray Diffraction (XRD), and Vibrating Sample Magnetometer (VSM). In the Fe10Al40(ZnO)50 nanocomposite, the crystallite size was determined to be at its minimum, measuring 27.30 ± 5.82 nm, with the lattice strain (ε) reaching its maximum value of 0.155 ± 0.008%. Similarly, Fe10Al50(ZnO)40 nanocomposite exhibited analogous trends in its structural and magnetic properties. Furthermore, the alteration in the mass ratio of aluminum and zinc oxide in the FeAlZnO nanocomposite influenced magnetic properties such as coercivity (Hc), magnetization saturation (Ms), magnetization remanence (Mr), and squareness (MR/MS). These findings indicate the potential of the FeAlZnO nanocomposite system as a high-frequency soft magnetic material.
