英文摘要	Longitudinally driven giant magnetoimpedance (GMI) effect has been measured in Fe(73.5)Cu(1)Nb(3)Si(13.5)B(9) 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 1.0 cm in length annealed at 480 degrees C, the maximum MI ratio of 10 906% was achieved at the frequency of 214 kHz. 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 k. (C) 2009 Society of Photo-Optical Instrumentation Engineers.
