Study of Laser Annealed Ferromagnetic Amorphous Ribbons by Scanning Electron-Acoustic Microscopy

Scanning Electron Acoustic Microscopy (SEAM) was developped in 1980 (l)(2) and has been mainly used in the last few years in the characterization of metals and semiconductors. SEAM has been also applied to the observation of different surface and subsurface features in ceramics (3) and domain walls in amorphous ferromagnetic alloys (4).
