Abstract

The present invention provides new amorphous Fe-based alloys of the formula FeaCrbNicMdBeSifPk , where M is at least one metal selected from the group consisting of Mn, Co, Mo, Nb, Hf, W, Zr, V and Al, where the sum a+b+c+d+e+f+k is essentially 100, wherein a ranges from about 40 to about 75 atomic %, b ranges from about 3 to about 14 atomic %, c ranges from zero to about 40% atomic %, d ranges from zero to about 20 atomic %, e ranges from about 5 to about 15 atomic %, f ranges from about 3 to about 10 atomic % and k ranges from about 0.1 to about 5 atomic %. The alloys of the invention are characterized by having low coercivity, high squareness, and high permeability, which implement their use in the production of markers in EAS systems or in the production of magnetic amplifiers.
