Model of the Magnetostrictive Hysteresis Loop with Local Maximum.

This paper presents a model of the magnetostrictive hysteresis loop with local maximum. The model is based on the differential equations describing magnetostriction due to the domain wall movement as well as domain magnetization rotation. The transition between these mechanisms of magnetization is quantified by the Maxwell⁻Boltzmann distribution. Moreover, the lift-off phenomenon in the magnetostrictive hysteresis loop is considered. The proposed model was validated on the results of measurements of magnetostrictive hysteresis loops of Mn0.70 Zn0.24 Fe2.06 O₄ ferrite for power application and 13CrMo4-5 construction steel. The results of modeling confirm that the proposed model corresponds well with experimental results. Good agreement was confirmed by determination coefficient R², which exceeded 0.995 and 0.985 for Mn0.70 Zn0.24 Fe2.06 O₄ ferrite for power application and 13CrMo4-5 construction steel, respectively.
