In the previous study, we have shown the consistency between the spectral characteristics of magnetoacoustic emission (MAE) and the effects of uniaxial stress, with an AC magnetic field applied parallel to the stress axis [1,2]. This is based on the following facts; first, the main contribution to MAE generation is due to the motion of 90° domain walls and, second, the uniaxial stress controls the area of 90° domain walls through the domain alignment [3]. The area of 90° domain walls decreases monotonically upon the application of tensile stress. At the initial stage of applying uniaxial compression, however, the area of 90° domain walls, contributing to the MAE generation, increases up to certain level of compressive stress and begins to decrease beyond that point. The amplitude of MAE burst was seen to follow the above-stated uniaxial stress effects on the area of 90° domain walls. More specifically, the MAE amplitude increased upon the application of compressive stress and reached its maximum in a range between −50 to −75 MPa.
