Abstract
Amorphous ferromagnetic alloys having a niobium content in the range of 2.5 to 15 atomic percent have been conceived. These alloys are obtained directly in the amorphous state or as a mixture of amorphous and crystalline places. These alloys have superior properties relative to prior known amorphous and some amorphous alloys. The amorphous ferromagnetic alloys of this invention are readily produced by rapid solidification techniques with no need for subsequent treatment.
