Abstract
The paper presents a theoretical study of the effect of torsional stresses on the giant magnetoimpedance of a Fe-rich amorphous microwire with helicoidal anisotropy induced in the surface layer as a result of annealing. It is shown that torsional stresses lead to a change in the shape of the dependence of the impedance of the microwire on an external field at relatively low frequencies of the excitation current. The change in impedance is maximal near the stress value at which an effective circular anisotropy in the surface region of the microwire appears. The results can be used to create stress and weak magnetic field sensors.
