Coexistence of very soft magnetism and good magnetoelastic coupling in theamorphous 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 so ft magnetic material that, after proper annealing, represents giant amplitu de of the resonant magnetoacoustic waves, at zero magnetising field. The ma in characteristic of the new material are reported with regard to the hyste resis cycle, the annealing effect on the structure and the dynamic magnetoe lastic coupling.
