✦ Synopsis

A study of thermal and magnetic properties and of the giant magneto-impedance (GMI) effect in cobalt-based amorphous alloy ribbons Co 80Àx Fe x B 10 Si 10 , with x ¼ 6, 8 and 10 is presented. The thermal and magnetic characterization was carried out using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), magnetization and magneto-impedance measurements. The ribbons exhibit ultrasoft magnetic behavior, especially GMI effect. Particular attention has been given to observation of crystallization kinetics.
