抄録
We investigated the magneto-acoustic excitation properties of amorphous iron-boron films prepared by rf-high rate sputtering by observing magnetoelastic wave resonance in linear samples. The longitudinal complex susceptibility was measured as a function of the external applied field. Films about 10 μm thick were deposited onto aluminum foil substrates. The observed magnetoelastic wave was a standing wave of the lowest mode. The controllable change in the velocity of sound by the application of an external field ΔC⁄C was about 4.7% for films with substrates. This value increased to 17% when films were removed from the substrate, the new value being comparable to that obtained in rapid-quenched Fe80B20 ribbons. The experimental results are explained very well by the one-dimensional string model, from which important magneto-acoustic quantities are derived.
