Effect of composition on the structural relaxation of amorphous iron-based alloys
The structural relaxation of iron-based amorphous alloys upon changes in their relative electrical resistance and magnetic moments upon a rise in temperature is investigated. The presence of Nb in Fe(Cu, Nb)–Si,B alloys stabilizes amorphous states, lowering the Curie temperature TCam and raising the temperature of the paramagnetic–ferromagnetic magnetic phase transition.
