“…It has excellent comprehensive soft magnetic properties such as high saturation magnetic induction intensity, high effective permeability, low dissipation and low coercivity. In addition, the low cost, simple preparation process and high heat resistance make it likely to become one of the most widely used ferromagnetic materials [3][4][5].…”

In order to explore the magnetic moment rotation in nanocrystalline soft magnetic alloys under high-frequency sinusoidal excitation, based on G. Herzer’s stochastic anisotropy theory and symmetry principle, a three-dimensional model of nanocrystalline alloy was established, and a sinusoidal alternating magnetic field with a frequency f of 1 kHz to 10 kHz and an amplitude H of 0.1 T to 0.8 T was applied to the model. The magnetic moment movement in the magnetization process is investigated at the mesoscopic and macroscopic levels by defining the magnetic moment deflection velocity ω and magnetization rate v, respectively. The results show that ω is positively correlated with the alternating magnetic field f and H, and the increase of f has a particularly significant effect on ω growth compared with the increase of H. Then the function relation between ω and f and H is obtained by fitting. In which the coefficient of f is much larger than that of H, about 2.5 times that of H. Finally, the magnetization curve is measured by an AC measuring device, and the functional relations between v and the alternating magnetic fields f and H are obtained, in which the coefficient of f is much larger than that of H, about 2.75 times that of H. This value is approximately the same as that of the ω analysis, at the same time the relative error is only 9.1%.
