This work has been supported by the Volkswagen Foundation and by CICYT (Project PB86-0151 and MAT 88-0646-CO3).Scanning electron acoustic microscopy (SEAM) has been used in the observation of domain walls in iron- and cobalt-based amorphous alloys ribbons. Controlled magnetic annealing experiments enabled the direct identification of domain walls in SEAM micrographs. Walls in perpendicular anisotropy regions of the high magnetostriction samples show a particular high contrast, probably related to the wall stress field.engjournal articlehttp://dx.doi.org/10.1063/1.106325http://scitation.aip.orgopen access538.9PhysicsAppliedFísica de materiales
