Abstract

Helical magnetic anistropy induced by current annealing under a constant torisional angle of 2Ox rad/m in two Co-rich amorphous wires with negative and nearly-zero magnetostriction is reported. The measurements were performed using the inverse Wiedemann effect hysteresis loop of the wires. Influence of preannealing on this kind of magnetic anisotropy in both wires is also analysed taking into account the anelastic and plastic contributions to this anisotropy
