Abstract
Soft ferromagnetic materials are very useful for many sensors using magnetic materials demanding high permeability,low coercivity and low hysteresis los. Among them, FeCoSiBNi amorphous magnetic films show a good impedanceby melt-spun method, one of the rapid solidification process. Ribbon shape wires were made from the films, and let themannealed in DC magnetic field to increase the maximum Giant Magneto Impedance ratio. Field annealing decreases thestress and changes the effective anisotropy. Thus, we can find that the impedance change (200.47 %) is improved andthe fabricated magnetic wire has characteristics of good sensor element.
