This paper reports the mechanism of sensitive and stable large Barkhausen effect of as-cast amorphous magnetostrictive wires having three composition systems investigated using measured values of stress induced anisotropy constant K{sub u}, saturation magnetostriction {lambda}, residual internal stress {sigma}{sub r}, and MH hysteresis loop squareness Mr/M{sub 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 are also investigated in magnetostrictive and non-magnetostrictive amorphous wires magnetized with a longitudinal AC field, AC wire current, or AC field perpendicular to the wire axis.
