“…Figure 13 shows typically measured hysteresis loops at B m = 1.5 T. For the compressed sample, a characteristic distortion of loop shape in the low field (Rayleigh) region is observed. It is similar to the shape of hysteresis loops for two-phase materials [49,50] or those measured in the transverse direction for highly anisotropic steels [2,3,[51][52][53][54][55]. Briefly speaking, this effect may be explained by the interchange of the roles of 180 • (Bloch) and 90 • (Néel) domain walls upon a specific threshold field.…”

Modeling of hysteresis loops may be useful for the designers of magnetic circuits in electric machines. The present paper focuses on the possibility to apply the Harrison model to describe hysteresis loops of grain-oriented electrical steel subject to compressive stress. The model extension is achieved by introduction of an additional term into the equation that describes irreversible magnetization process. The extension term does not include a product of stress and magnetization, as could be anticipated from Sablik’s theory, applicable, e.g., to the Jiles–Atherton model. The present contribution points out the fundamental differences between the two aforementioned modeling approaches, which are based on different philosophies despite some apparent similarities. The modeling results are in a qualitative agreement with the experimental results obtained from a single sheet tester for a representative commercially available grain-oriented electrical steel grade 0.27 mm thick.

“…The encouraging modeling results indicate that the considered relationships (1)-(4) might be introduced into some advanced hysteresis models like the description advanced by Jiles and Atherton [18]. Thus future work shall focus on a comparison of the approach relying on the introduction of relationships (1)- (4) into the macroscopic hysteresis model with the existing phenomenological extensions [19][20][21][22].…”

Magnetic properties of grain-oriented steels are inseparably linked to their anisotropy. A proper characterization of anisotropy is thus crucial for practical applications. In the paper a description based on magnetic measurements carried out for three well-defined cutting angles is presented. It is shown that it is possible to predict magnetic properties of interest (coercive field strength, remanence flux density) for an arbitrary angle using a limited number of measurements.

“…Most papers devoted to the JA model focus on the following issues: estimation of model parameters using different techniques [14,[57][58][59][60][61][62][63][64], analysis of coupled problems [10,12,53,65,66] and possibilities of the model to describe magnetization processes in novel materials and structures [3,58,[67][68][69][70]. A number of references report on the necessity to update the values of some model parameters in order to obtain a quantitatively correct representation of minor loops and reversal curves [14,18,51,57,58,68,71,72].…”

This paper focuses on the problem of how reversible magnetization processes are taken into account in contemporary descriptions of hysteresis curves. For comparison, three versions of the phenomenological T(x) model based on hyperbolic tangent mapping are considered. Two of them are based on summing the output of the hysteresis operator with a linear or nonlinear mapping. The third description is inspired by the concept of the product Preisach model. Total susceptibility is modulated with a magnetization-dependent function. The models are verified using measurement data for grain-oriented electrical steel. The proposed third description represents minor loops most accurately.
