Surface Barkhausen noise (SBN) measurements were mae on a 2-percent Mn pipeline steel sample subjected to different levels of applied tensile and compressive isostress. The magnetic field direction was varied through a full 360{degrees}. SBN voltage was found to depend on both stress level and magnetic field direction. The results were analyzed in terms of the reorientation of magnetic moments from axial to circumferential directions with increasing tension. Compression was found to re-align the magnetic moments in the axial direction.
