In this work we report some results concerning the torsion impedance of amorphous Co sub 68.1 Fe sub 4.4 Si sub 12.5 B sub 15 wires in the as-cast state, and after a stress annealing treatment. The influence of the drive current amplitude and frequency is also studied for these samples. A sensitivity to the applied torsion up to 17.6%/rad m is obtained for the annealed wire. The magnetoimpedance response of both types of samples gives evidence to the difference in their domain structure.
