Abstract
Low-field magnetoacoustic responses in steel have shown a distinctive effect of static uniaxial compressive stress by giving initial negative slopes of acoustic natural velocity curves obtained as a function of net magnetization induced parallel to the stress axis. Such an effect of uniaxial compressive stress has been explained by a model based on field induced-90° domain wall motions. The model also predicts the appearance of initial negative slopes under uniaxial tensile stress if net magnetization is induced perpendicular to the stress axis, even though the effect would be smaller under this condition. The weak uniaxial stress dependence for perpendicular magnetization is a result
