Abstract

The mechanism of the sensitive and stable large Barkhausen effects of as-cast amorphous magnetostrictive wires having three composition systems was investigated using measured values of stress-induced anisotropy constant saturation magnetostriction, residual internal stress, and MH hysteresis loop squareness M_r/M _s. The entire composition range of FeCo is compared to FeCr with up to 10 at.% and FeNi with Ni up to 12 at.%. Matteucci effects were also investigated in magnetostrictive and nonmagnetostrictive amorphous wires magnetized with a longitudinal AC field, AC wire current, or AC field perpendicular to the wire axis
