Abstract: Amorphous Fe73.0Cu1.0Nb1.5V2.0Si13.5B9.0 microwires were prepared by glass-coated melt-spinning technique. Nanocrystalline samples were obtained by annealing the amorphous wires at appropriate temperatures and the longitudinally driven giant magneto-impedance effect has also been investigated for the first time. The result showed that the maximal magneto- impedance value was 1020% obtained in the sample annealed at 5700℃.

Key words: giant magneto-impedance(GMI), longitudinally driven, Fe-based nanocrystalline microwires, giant magneto-impedance(GMI), longitudinally driven
