摘要：

It is shown that in appropriate experimental conditions a direct relation between the magnetoelastic coupling coefficient k and the amplitude A(o) of resonant magnetoelastic longitudinal waves can be demonstrated in ribbons of soft ferromagnetic metal. The model conclusions on the behaviour of A versus k were experimentally verified in Fe73.5CuNb3Si13.5B9 amorphous alloy; k optimization were produced by both heat induced structural relaxation and nanocrystallization. Since k is directly dependent on Young modulus, a comparison, both experimental and theoretical, between Young modulus behaviour and magnetoelastic waves amplitude in resonance conditions is consequent.
