Abstract
Scattered magnetoelastic waves were observed in as-quenched and annealed amorphous Fe-Si-B wires in order to clarify the nature of the scattering centers. Neither magnetic field nor tensile stress applied to the wire change the waveform of the scattered wave. Scattered waves observed in annealed wire show that the annealing process has no significant effect on the properties of the scattering centers. These experimental results indicate that the scattering centers are caused by fluctuations of some elastic properties along the wire introduced by the quenching process, and that they have an average interval of a few millimeters.Keywords
