Abstract
An improved technique was developed for measuring the attenuation constants of magnetoelastic waves in amorphous wires under an arbitrary magnetic field. Measured attenuation constants in an as-quenched, a wire-drawn, an annealed, and an annealed-after-drawn Fe-Si-B wire were shown as a function of a magnetic field applied to the sample wires. An extremely large value of the attenuation constant was observed in the annealed wire under no magnetic field. The value decreased rapidly when a magnetic field was applied to the wire. We also showed that the dependence of the attenuation constant on the magnetic field can be used to control the amplitude of the magnetoelastic waves.Keywords
