“…Next, the included angle between each unit magnetic moment and the positive X-axis in the figure is calculated by the coordinates of the magnetization vector m. Then, take the arithmetic average of all the angles obtained to get the θ value at the corresponding time. Finally, the included angles at all times can be obtained by repeating the above steps, and the deflection angular velocity ω of the magnetic moment can be obtained through calculation of Equation (2). Table 3 lists the value of magnetic moment deflection angular velocity ω of material under the excitation of an alternating magnetic field, frequency f is 1 kHz-10 kHz and amplitude H is 0.1 T-0.8 T. Based on the data in Table 3, the variation curves of magnetic moment deflection angular velocity ω and alternating magnetic field frequency f and amplitude H are drawn, as shown in Figure 13.…”

“…With the continuous expansion of long-distance DC power transmission and gridconnected energy storage systems in China, high-frequency transformers, which realize DC voltage conversion and energy exchange through high-power electronic devices and their control technology, has shown great advantages and gained extensive attention [1,2]. Compared with the power frequency transformer, the high-frequency transformer has the advantages of small size, more energy transfer and constant voltage output on the load side.…”

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%.

Fe‐based amorphous alloy coatings (Fe‐AACs) have exhibited appropriate corrosion and wear resistance and improve the performance of material surfaces. This study summarizes the advances related to Fe‐based amorphous alloys pertaining to their chemical compositions and manufacturing processes and their associated effect on the amorphous structure, microstructure and properties. In particular, Fe‐based amorphous alloy coatings produced by laser cladding are investigated in order to study the effect of amorphous structure, partial crystallization, and composition on the microstructure, hardness, corrosion and wear resistance of these coatings. In addition, the effect of laser parameters (power and scanning speed) on the geometric and metallurgical characteristics of produced amorphous coatings are also covered.This article is protected by copyright.
