Coexistence of very soft magnetism and good magnetoelastic coupling in the amorphous alloy Fe62.5Co6Ni7.5Zr6Cu1Nb2B15

Amorphous ferromagnetic ribbons in a new composition were prepared by melt spinning. The alloy components were calibrated in order to obtain a very soft magnetic material that, after proper annealing, represents giant amplitude of the resonant magnetoacoustic waves, at zero magnetising field. The main characteristic of the new material are reported with regard to the hysteresis cycle, the annealing effect on the structure and the dynamic magnetoelastic coupling.
