摘要：

We report in this work the behaviour of the magneto-impedance in twisted wires of amorphous Co68.1Fe4.4Si12.5Bi15 that have been subjected to a current annealing with an applied tensile stress and have various induced anisotropies and saturation magnetostriction coefficients. The samples were annealed at 0.5 A for 1 min, with applied stresses in the range 100-800 MPa, The magneto-impedance is studied in the best frequency and current-amplitude ranges. High sensitivities to the applied magnetic field (up to 200% Oe(-1)) and to the torsion (around 940% rad(-1) cm) are obtained.
