The objective of this study was to examine and compare the structural, and magnetic properties of two alloys, namely Ni80Fe20 and (Ni80Fe20)90Cu10, which were fabricated using mechanical alloying. The milled samples were analyzed using x-ray diffraction, scanning electron microscopy, energy dispersive x-ray spectroscopy, and vibrating sample magnetometer. These techniques were employed to assess and characterize the alloys regarding their structural composition, morphology, and magnetic properties. In both composition alloys, the coercivity values displayed an increasing trend. However, the rate of increase was comparatively lower for the (Ni80Fe20)90Cu10 alloy than that the other alloy. In the annealed last stage sample of the (Ni80Fe20)90Cu10 alloy at 650 °C, a significant increase in magnetic saturation and a drastic decrease in coercivity value to as low as 6 Oe were observed. These findings indicated that the (Ni80Fe20)90Cu10 alloy can be considered a promising candidate for a soft magnetic alloy, as it demonstrates improved magnetic properties with enhanced saturation and reduced coercivity.
