“…The parameters were estimated using the major hysteresis loop measured at quasi-static conditions, B m = 0.6 T. The bounds for model parameters were determined using the empirical guidelines as given in Ref. [2]. The bounds for the parameter γ were set to [0.01;0.5], whereas for the parameter H HS - [2;7] (its value should correspond to the measured quasi-static coercivity).…”

The paper focuses on the estimation techniques for a low-dimensional phenomenological model of ferromagnetic hysteresis proposed by the Brazilian research group GRUCAD. The description is expressed with an ordinary differential equation and some auxiliary relationships. It describes both irreversible and reversible magnetization processes and addresses some problems inherent in the well-known Jiles-Atherton model. It is found that the differential evolution method is the most competitive technique for recovery of optimal model parameters.

The paper presents the results of the magnetoelastic Villari effect modelling in high-permeability Mn0.51zn0.44Fe2.05O4 ferrite. Modelling was performed on the basis of measurements of magnetoelastic characteristics of frame-shaped samples. For the modelling, the corrected Jiles-Atherton-Sablik model was used. On the base of modelling results, the stress dependence of parameter k and stress-induced anisotropy were estimated. As a result the changes of saturation magnetostriction of Mn0.51zn0.44Fe2.05O4 ferrite subjected to stresses were calculated. Such changes were previously observed experimentally. However, the phenomenon of stress-induced sign change of saturation magnetostriction was never previously explained quantitatively.

“…Since its introduction [1] in 1984 this model was developed and updated considering different physical phenomena, such as uniaxial or cubic anisotropy of magnetic material [2,3], dynamic magnetization [4], as well as advanced methods of determination of model parameters [5][6][7]. Moreover, different computational issues connected with Jiles-Atherton model were considered [8], mostly caused by solving of differential equations stating the model.…”

Jiles-Atherton model is one of the most advanced and most popular models of magnetic hysteresis loop. However, this model is considering different physical phenomena and computational issues. As a result, cross-validation of the results of modelling performed by different authors became difficult. For this reason, the open-source MAT-LAB/OCTAVE based implementation of Jiles-Atherton model was developed. Proposed implementation covers isotropic model of magnetic hysteresis loops as well as uniaxial and grain oriented electrical steel anisotropy. Moreover, the corrections proposed by Venkataraman together with different approaches to derivative of the anhysteretic magnetization are considered. Developed library is freely available together with the examples of magnetic hysteresis loops. As a result, it can be the base for further development of Jiles-Atherton model for better understanding of magnetization process as well as modelling the inductive components.
