Abstract
The giant magneto-impedance (GMI) effect was investigated in the nanocrystalline FeCuNbSiB multilayered films in the present paper. The results indicate that the maximum LMI ratio was 44% at the frequency of 3 MHz, and the maximum TMI ratio was 46% at the frequency of 6 MHz, respectively. The TMI spectra have a threshold field. While the magnetic field is bigger than the threshold field, the magneto-impedance was evidently decreased. In the nanocrystalline multilayered films, the frequency of the maximum LMI ratio is lower than its amorphous multilayered film. The GMI ratio of multilayered films was changed following the orientation of magnetic moments. When the orientation of moments was perpendicular to the film plane, the GMI ratio was dramatically decreased.
