Longitudinally driven giant magnetoimpedance (GMI) effect has been measured in ribbons, and the enhancement of GMI effect using magnetoelastic resonance was investigated. The results showed that at a certain driven frequency when magnetoelastic resonance occurred, there was a great enhancement of the impedance of the element and MI effect. For the ribbon of in length annealed at , the maximum MI ratio of 10 906% was achieved at the frequency of . The maximum sensitivity reached up to 5 155%/Oe, which was almost 40 times higher than that observed in traditional MI measurements. The results demonstrated that the enhanced magnitude of MI effect mainly depended on magnetoelastic coupling coefficient .
