Domain wall processes (domain wall configuration, propagation and collapse) in magnetostrictive amorphous wires of the composition (Fe[sub 77.5]Si[sub 7.5]B[sub 15]) were investigated. The wires were held under tensile stress (up to 1700 MPa in the case of as-quenched). The domain wall length and normal mobility (or damping) as functions of applied stress were found experimentally and theoretically from an ellipsoidal domain model. This allows the losses to be separated into eddy current and spin relaxation contributions. It was demonstrated that the process of domain collapse affected by internal magnetic field generated a very sharp voltage pulse. The change in the voltage pulse shape with increase of tension was investigated as well.
