“…It is also important to notice the paramount role of the effective field in any attempts to develop hysteresis models compliant with thermodynamics of irreversible processes [6,7]. It has been shown that the introduction of the positive feedback mechanism expressed by the effective field either improves the overall accuracy of other hysteresis models or constitutes their foundations [28,35,44,61,70]. The effective field term in the J-A model has been extended to take into account a number of phenomena affecting the shape of hysteresis loop, e.g.…”

Some physical concepts important for a hysteresis model (effective field, anhysteretic magnetization) are discussed on the example of Jiles-Atherton model. The Jiles-Atherton model reveals some drawbacks, which make this model more difficult to be applied in electrical engineering. In particular, it does not describe accurately the magnetization curves after a reversal, moreover complex magnetization cycles are poorly represented. On the other hand, the phenomenological description proposed by Takács seems to be a valuable alternative to the Jiles-Atherton formalism. The concept of effective field may be easily incorporated in the description.

“…The AM curve is the basis of Jiles-Atherton model [1,2] and its modifications [3,4]. The Harrison model is also based on the AM curve [5]. The basic models of the AM curve itself, however, have not been validated experimentally for novel magnetic materials.…”

The anhysteretic magnetization curve is the key element of modeling magnetic hysteresis loops. Despite the fact that it is intensively exploited, known models of anhysteretic curve have not been verified experimentally. This paper presents the validation of four anhysteretic curve models considering four different materials, including isotropic, such as Mn-Zn soft ferrite, as well as anisotropic amorphous and nanocrystalline alloys. The presented results indicate that only the model that considers anisotropic energy is valid for a wide set of modern magnetic materials. The most suitable of the verified models is the anisotropic extension function-based model, which considers uniaxial anisotropy.

“…The study of phase transitions in magnetocaloric materials requires that new computational tools able to capture the effect of varying temperature on the shape of magnetization curve be developed [7][8][9][10]. In our opinion a convenient description for this purpose could be the Harrison model [11][12][13].…”

Modeling of hysteresis loops close to the Curie point may shed some light on physics of magnetization processes in magnetocaloric materials. In the present paper the model advanced by Harrison is used to describe magnetization curves of La(Fe,Co,Si)13 alloy. Systematic study has revealed that values of some model parameters depend significantly on temperature. The trends of their variations are discussed in the paper.
