Modeling of Magnetostriction Curves of Ni Based on Jiles-Atherton Type Differential Hysteresis Model

Year: 2025

Type: article

Abstract: Magnetostriction is a typical magneto-mechanical phenomenon observed in magnetic materials, which is accompanied by hysteresis.In this paper, we attempt to modify the Classical Jiles-Atherton model (CJA model), which is a typical differential hysteresis model of a magnetization process, into a hysteresis model of magnetostriction curve.At first, we compared the hysteresis of the magnetization curves and the magnetostriction curves and clarified the differences.Then, we proposed a method to incorporate the "proceed" characteristics of the magnetostriction hysteresis curves into the CJA model.Finally, to verify the correctness of the modifications, the proposed model was checked to see if it could represent the experimental data of nickel measured under several uniaxial stresses.The verification results show that the magnetostriction curves of nickel can be represented with high accuracy using the proposed Jiles-Atherton type differential hysteresis model.
