초록

Nickel rich amorphous ferromagnetic alloys having a nickel content in the range of 35 to 55 atomic percent have been conceived. These alloys are in the amorphous state and exhibit high permeability relative to prior known amorphous ferromagnetic alloys. These nickel rich alloys can be produced by rapid solidification techniques without the need of subsequent heat treating.
