Abstract

The ΔE effect is often presented as the dependency of the Young's modulus of a material on its state of magnetization. Nevertheless, the elastic properties of a magnetic material do not depend on the magnetization state. Actually, the sensitivity of the magnetostriction strain to the application of a stress explains the ΔE effect. According to this statement, a semi-analytical model for the ΔE effect is proposed, in which magnetization rotation is not considered. An experimental procedure to measure the ΔE effect in magnetic materials is then built-up. Experimental and modeling results are finally compared, with satisfying agreement.
