Effects of wire-drawing and annealing on propagation of magnetoelastic waves in amorphous wires

Propagation behaviors of magnetoelastic waves in amorphous wires are studied in respect to the dependence of them on annealing, wire-drawing and etching treatments. The scattering centers for the magnetoelastic wave are suggested to exist extensively all over the volume of as-quenched sample wires produced by the in-rotating-liquid spinning method. The wire-drawing treatment is exceedingly effective in removing these scattering centers for the magnetoelastic wave. An annealing after wiredrawing treatment is needed for softening the magnetic hardness arising from the wire-drawing treatment.
