摘要：

A giant stress-impedance (GSI) effect with a strain gauge factor of more than 5000 was observed in initially amorphous Fe7:.5Cu1Nb3 Si13.5B9 ribbons annealed at 600degreesC for 30 min. The components of resistance R and reactance X of the complex impedance Z = R + iX, as well as the relative effective permeability mu(eff), for as-quenched and thermally annealed Fe73.5Cu1Nb3Si13.5B9 ribbons have been studied as functions of longitudinal applied tensile stress. The reactance X dominates the GSI effect and a maximum GSI ratio of 25% is observed for the sample annealed at 600degreesC for 30 min. The effective permeability has been shown to be responsible for the GSI effect. (C) 2003 Elsevier B.V. All rights reserved.
