The dc magnetic properties of amorphous wire having composition Fe77.5Si7.5B15 have been investigated in its as-quenched and flash-annealed states under tensile stress (σ). A large Barkhausen jump in the magnetization M* is observed at the switching field H*. The variation of the switching field with applied stress is found to be more sensitive in the as-quenched state compared with the flash-annealed one. A linear variation of M* with σ is found in the as-quenched and the flash-annealed states of the wires. The results on the remanence and the coercivity of the wires are presented. The increase in the remanence with stress is shown to follow from the domain structure of the wire. © 1992.
