Indirect effect of Si on the ferromagnetic transformation of Mn in FeCoMnAlSi high-entropy soft magnetic alloy
Source abstract
Abstract
In this study, we examined the indirect impact of Si on the ferromagnetic transformation of Mn in (Fe 0.8Co 0.2) 80-xMn 10Al 10Si x ( x = 0, 1, 2, 3, 4, & 5 at%) high-entropy soft magnetic alloys. Our findings indicate strong correlation between Si and the ferromagnetic transformation, substantiated by simulation calculations. With Si content increasing the saturation magnetization of the system exhibits a distinctive trend of an initial increase followed by a subsequent decrease. Notably, the coercivity consistently decreases with x increases. Remarkably, when x equals 3, the soft magnetic properties of the system reach an optimal state, characterized by a saturation magnetization of 186.5 emu·g −1 and a coercivity of 1.6 Oe. The density of states and magnetic moment of the system are obtained by simulation calculation. Notably, the average atomic magnetic moment of Mn (1.642 μ B) surpasses that of Co (1.434 μ B ), suggesting the excellent soft magnetic properties inherent in the system.
