Abstract (en)
[origin: EP0086485A2] A wound iron core by winding a thin strip of a soft magnetic alloy into a triodal form, characterized in that a Cobase amorphous magnetic alloy is used as the thin strip and that the thin strip is annealed in a magnetic field in the direction of excitation, so that the core exhibits a rectangle ratio Br/B10 of 85% or higher in D.C. hysteresis curve. The Co-base amorphous magnetic alloy has a composition substantially expressed by: Co100-a-bXaYb where X represents one, two or more elements selected from a group consisting of Ti, V, Cr, Mn, Fe, Ni, Zr, Nb, Mo, Ru, Hf, Ta, W, Y, Ce, Pr, Nd, Sm, Eu, Gd, Tb and Dy, while Y represents one, two or more elements selected from a group consisting of B, C, Al, Si, P and Ge, and wherein the following conditions are met: 0 </= a </= 15 (atom%) and 14 </= b </= 30 (atom%).
