Zero magnetostriction and low field magnetic properties of Co-Fe base amorphous alloys containing V,Nb,Ta,Cr,Mo,W,Mn or Ni

Abstract

Low‐field magnetic properties of the zero magnetostrictive amorphous ribbons of (Co, Fe, M)₇₈Si₈B₁₄ alloys (M=V,Nb,Ta,Cr,Mo,W,Mn or Ni) have been investigated. In all of these systems, the zero magnetostriction lines are located in the iron poor side less than 10 at%. The alloys containing VA and VIA group elements show highly improved low‐field magnetic properties with the effective permeability exceeding 10⁵ and the coercive force less than 2 mOe after the optimum heat treatment.
