Аннотация:The influence of torsional stress on the asymmetric magnetoimpedance in a glass-coated negative
magnetostrictive amorphous microwire due to bias current is studied theoretically.The longitudinal and off-diagonal impedance components are found.onalstress.The asymmetry in the field dependence of the impedance components is attributed to the combination of the circular magnetic field produced by the bias current and a helical anisotropy induced by the torsional stress.The asymmetry in the magnetoimpedance and the low-field hysteresis are analyzed as a function of the bias current and torsional stress.
