Description
Summary:Paper presents analysis of sensitivity of parameters of Jiles-Atherton model determined during the optimization process. Recently implemented, differential evolution based method together with two-step optimization process proved, that parameters of Jiles-Atherton model can be determined in reasonable time. However, paper indicates, that in the case of isotropic materials, Bloch domain wall interaction coefficient α has too insignificant influence on the shape of hysteresis loop to be determined during the optimization. As a result, for fundamental physics analyses, α should be estimated on the base of physical properties of magnetic material.
