摘要:
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.
