Abstract (en)
[origin: WO0030131A1] The magnetic core (M) consists of a coiled amorphous ferromagnetic alloy strip (B) Its saturation-permeability is greater than 20 000 and lower than 300 000. The saturation-magnetostriction of the magnetic core (M) is less than 0.5 ppm. The core (M) is substantially free from mechanical stress and has an anisotropic axis (A) along which the magnetization of the magnetic core (M) can be oriented in a particularly easy manner and which is perpendicular to a plane in which the center line of the strip (B) runs. The composition of the alloy essentially corresponds to the formula Coa(Fe1-xMnx)bNicXdSieBfCg whereby X is at least one of the elements V, Nb, Ta, Cr, Mo, W, Ge, P, a g is indicated in atom % and a, b, c, d, e, f, g and x meet the following conditions: 40 </= a </= 82; 3 </= b </= 10; 0 </= c </= 30; 0 </= d </= 5; 0 </= e </= 20; 7 </= f </= 26; 0 </= g </= 3; with 15 </= d + e + f + g </= 33 and 0 </= x </= 1.
