Propagation and reflection properties of magnetoelastic waves in Fe77.5Si7.5B15 amorphous wires are studied. The attenuation constant increases with increasing the driving frequency of the wave. As the attenuation constant of the wave driving at 500 kHz is quite small (0.18 m(-1)), the wave is expected to be observed after the propagation of 20 or 30 m. As for the reflection, the magnetoelastic wave is reflected with the efficiency as much as 0.9 at the driving frequency below 2 MHz using a clamp as reflector. (C) 1996 American Institute of Physics.
