“…A series of hysteresis models, such as Preisach [16]and J-A(Jiles-Atherton) [6,7,17], have been developed to describe the nonlinear magnetization state of soft ferromagnetic shielding materials. Among them, the J-A hysteresis model has a clear physical meaning, which is constructed by describing the wall movement law of magnetic domains under the pinning-rolling effect, and can accurately describe the nonlinear relationship between the magnetic induction strength and the magnetic field strength [17].…”

The study of the magnetic properties of nanocrystalline materials under stress is of great significance for the construction of small and lightweight magnetic shielding rooms. Therefore, this paper investigates the effect of stress on the magnetic properties of nanocrystalline materials under the action of external bending stress. By comparing the test results of the soft magnetic measuring device with and without bending stress, it is found that the magnetic permeability (μi) decreases by about 51.41% when the introduced bending stress σ is increased by about 5.96"×" 107 pa, whereas the "K" _"u" ^"Fe-Si" (induced magnetic anisotropy constant) and "H" _"k" (field of magnetic anisotropy) increase by 5.30"×" 102 J/m3and 1.08"×" 102 A/m, respectively. The Jiles-Atherton (J-A) model considering the bending stress and radius of change correlation is established, and the typical parameters of the J-A model are fitted using the Gazelle Optimization Algorithm (GOA), and the RMSE (root mean square error) of all of them are less than 0.056 T. The magnetic domain density increased with the increase of bending stress, which verified the correlation between the J-A model parameters and the bending stress. Our results reveal that the nanocrystalline macroscopic and micromechanical magnetic properties can be effectively combined with the J-A model, which will provide a theoretical basis for the simulation study of the nanocrystalline magnetic shielding device in the actual stress situation.

“…Nanocrystalline alloys have the advantages of low coercivity, low losses, high saturation magnetic induction strength, and high permeability [3][4][5][6]. In recent years, amorphous and nanocrystalline alloys have extensively used in transformers, mutual inductors, magnetic shielding, electromagnetic switches and other fields [7][8][9][10]. In the application of nanocrystalline alloys, their inherent nonlinear hysteresis characteristics will have a momentous impact on the electromagnetic field, excitation current and energy loss of power equipment.…”

The magnetic characteristics of Fe-based nanocrystalline alloys can be influenced by temperature. The conventional dynamic Jiles–Atherton (J-A) hysteresis model does not take into consideration the impact that temperature has on magnetic characteristics. A novel variable-temperature dynamic J-A hysteresis model is proposed in this paper to effectively address the issue. Firstly, the hysteresis loops of Fe-based nanocrystalline are measured at −50 °C–130 °C and DC state. The five parameters of the J-A hysteresis model are identified at various temperatures using the particle swarm optimization algorithm, and five parameters are fitted as functions of temperature. Subsequently, the five parameters as functions of temperature are introduced into the conventional dynamic J-A hysteresis model to construct a novel variable-temperature dynamic J-A hysteresis model, which can not only reflect the impact of temperature but also accurately calculate the losses. Finally, hysteresis loops and losses of Fe-based nanocrystalline alloy are simulated and calculated at different temperatures and frequencies by the variable-temperature dynamic J-A hysteresis model. Meanwhile, this paper also investigates the trends and percentages of hysteresis loss, excess loss as well as eddy current loss with frequency and temperature. Compared to the results of measured data, the maximum average error of the variable-temperature dynamic J-A hysteresis model is 5.83%.

“…[4,5] Nevertheless, the undesirable glass forming ability (GFA) and relatively low saturation magnetization are main challenges for their extensive use in energy-conversion devices. [6,7] To tackle these problems, repeated attempts have been made to improve the GFA and saturation magnetization simultaneously. [8][9][10] Several investigations have shown that the late transition metals (LTMs) and metalloids (M) are suitable microalloying elements for enhancing the GFA and soft magnetic properties.…”

This work aimed to tune the comprehensive properties of Fe-P-C-based amorphous system through investigating the role of microalloying process on the crystallization behavior, glass forming ability (GFA), soft magnetic features, and mechanical properties. Considering minor addition of elements into the system, it was found that the simultaneous microalloying of Ni and Co leads to the highest GFA, which was due to the optimization of compositional heterogeneity and creation of near-eutectic composition. Moreover, the FeCoNiCuPC amorphous alloy exhibited the best anelastic/viscoplastic behavior under the nanoindentation test, which was owing to the intensified structural fluctuations in the system. However, the improved plasticity by the extra Cu addition comes at the expense of magnetic properties, so that the saturation magnetization of this alloying system is significantly decreased compared to the FeCoPC amorphous alloy with the highest soft magnetic properties. In total, the results indicated that a combination of added elemental constitutes, i.e., Fe69Co5Ni5Cu1P13C7 composition, provides an optimized state for the comprehensive properties in the alloying system.
