MODELS OF JILES-ATHERTON HYSTERESIS LOOPS AND MODELS OF MAGNETIZATION CURVES FOR MAGNETICALLY SOFT AMORPHOUS ALLOYS
Abstract
Two models of remagnetization of soft-magnetic amorphous alloys are considered: the Jiles-Atherton hysteresis model and a model of the magnetization curve. The aim of the research is to evaluate models according to the criteria of simplicity of the mathematical expressions obtained and the adequacy of the description of the magnetization phenomenon. The relative error of modeling is chosen as a criterion for the accuracy of the model. In the study, the least squares method was used to model the main magnetization curve and the method of optimizing the Jiles-Atherton hysteresis curve using experimental and reference data. It is concluded that both models of magnetization of magnetically soft amorphous alloys give approximately the same modeling accuracy.
