中文摘要	Co-based Co63Fe4B22.4Si5.6Nb5 amorphous ribbons with a width of 150 μm and a thickness of 50 μm were prepared by sin-gle-roller melt-spinning process. The giant magneto-impedance (GMI) effect of the stress-joule-heated ribbons under applied tensile stress ranging from 37 to 148 MPa was investigated. Experimental results show that the spectra of GMI ratio vs. exter-nal direct current (dc) field (Hex ) of the samples changes dramatically with annealing tension (？) and driving frequency. The single-peak (SP) GMI curve with maximum GMI ratio of 260% and magnetic field sensitivity of 52%/Oe was obtained in the sample applied tensile stress of 74 MPa at frequency of 3.6 MHz. A three-peak behaviour appeared in the samples under σof 111 and 148 MPa. The uncommon three-peak behaviour was attributedto several factors, which effectively originated from the balance between domain-wall movement and magnetization rotation.
