Generation and Propagation of Magnetoelastic wave in Amorphous Wire

Magnetoelastic wave propagation in amorphous wire was observed. The dependence of the attenuation constant on the magnetic field was determined by applying a dc field to the propagation path. Comparison with results obtained for amorphous ribbons showed that despite the measurement made at a higher frequency, the attenuation constant for the wire at high fields was lower, confirming that measurements can be made for wires at higher frequencies than for ribbons.
