综述了 Preisach 模型在软磁材料微观结构与磁滞相互作用研究中的应用。结果表明，平均场效应主要是由于总磁畴壁表面能沿磁滞回线的变化造成的。讨论了根据一组适当的实验数据重建 Preisach 分布，并介绍了部分结晶 FeCoB 非晶合金中重建分布的微观结构演变。最后，在最近提出的 Preisach 模型动态推广的框架中讨论了快淬 6.5% SiFe 合金中的动态滞后效应问题。
The application of Preisach modelling to the study of the microstructure-hysteresis interplay in soft magnetic materials is reviewed. It is shown that mean-field effects are mainly due to the change of the total domain wall surface energy along the hysteresis loop. The reconstruction of the Preisach distribution from a proper set of experimental data is discussed and the microstructural evolution of the reconstructed distribution in partially crystallized FeCoB amorphous alloys is presented. Finally, the problem of dynamic hysteresis effects in rapidly-quenched 6.5% SiFe alloys Is discussed in the frame of a recently proposed dynamic generalization of the Preisach model.
