“…The first group are physical models, which are very complex and connect physical properties of the ferromagnetic material with its magnetic characteristics. The most important of these models are the Jiles-Atherton model [2][3][4], the Harrison model [5,6] and the Preisach model [7,8]. Physical models are relatively hard for implementation because of their complexity and high computing power required to perform the necessary calculations.…”

The following paper presents the basis of a Rayleigh magnetic hysteresis model and the examples of its application for modeling the magnetic characteristics of ferromagnetic materials: ferrites and steels. The presented model allows one to simulate the shape of a magnetic hysteresis loop of the material for the given value of the magnetizing field in the so-called Rayleigh region, as well as to calculate basic magnetic parameters of the material like coercive field, magnetic remanence, and power loss. Four different ferromagnetic materials (two ferrites and two alloy steels) were chosen for the investigation. Each material was investigated within the range of low magnetizing fields, corresponding to the Rayleigh region. On the basis of obtained results, modeling of magnetic characteristics of the investigated materials was performed. Moreover, the range of magnetizing field where the Rayleigh model can be applied for these materials was investigated based on correlation coefficient between experimental results and modeling.

“…Best results were achieved for Lorentzian curve [9]. For two-dimensional model Gaussian probability density function gave good conformity with measured data [5]. There were three reasons why good conformity for Gaussian distribution was achieved.…”

“…Less important are the so called Néel walls, which on the other hand are crucial for thin films and ribbons that can be approximated by two-dimensional domain structure model such as the Van den Berg construction [4]. Distribution of magnetic moments in thin cores was simulated in [5] and [6]. For both domain wall types external magnetic field vector and domain magnetization vector are on the same rotation plane.…”

In this paper possibility of application two-dimensional vector Preisach model for bulk materials was investigated. Physical magnetization mechanisms in bulk cores and thin ribbons were analyzed. Model is based on collection of the Preisach planes which describe material state in different angles on rotation plane. Presented model exhibits good conformity with experimental data for bulk as well for ribbon shaped cores. Model includes anisotropy and describes not only mean magnetization vector, but also distribution of magnetic moments for different angles.

“…Domain rotation process occurs for higher magnetic field values than domain wall motion. The magnetic field value, for which rotation process starts depends on saturation field, coercive field and angle between domain orientation and external magnetic field vector [7]…”

Extended Preisach model parameters can be strongly related to microstructural properties of material. It can also include real physical magnetization mechanisms such as domain wall motion and domain rotation. This paper shows that Preisach model is able to anticipate different phases in material structure. Existence of different phases in the material are due to thermal treatment, which is used to improve magnetic properties of amorphous alloys. Model was verified using ring shaped cores made of bilayered amorphous ribbons, which served as a physical model of the loosely coupled two phase ferromagnetic material with distinct magnetic properties.
