The stress-impedance (SI) effect has been observed in as-cast and high-current-density electropulsing annealedFe73.5Cu1- Nb3Si13.5B9 ribbons. Large SI ratios of -35% and 25% have been obtained in high-current-densityelectropulsing annealed samples but not in as-cast samples. The SI effect changes drastically with the den-sity of the annealing current and the longitudinally applied stress during the annealing process. The effectivepermeability has been shown to be responsible for the SI effect.
