Abstract :

The influence of direction and strength of induced magnetic anisotropy on stress-impedance (SI) effect was experimentally and theoretically studied in this paper. Experimentally, it was found that the magnetic anisotropy of the stress Joule heated Fe_73.5Cu ₁Nb₃Si_13.5B₉ nanocrystalline ribbons were determined by direction and strength of the induced anisotropy. Theoretical calculations of the direction and strength of the induced magnetic anisotropy suggest that transverse anisotropy and small anisotropic field result in an increase of the SI effect. To decrease the anisotropic field and increase the transverse anisotropy simultaneously, a complex annealing process was applied to Fe_73.5Cu₁Nb₃Si_13.5B₉ ribbons, and it was found that the SI effect was drastically improved. A maximum change of 286% in the SI ratio of the complex annealed nanocrystalline Fe_73.5Cu₁Nb₃Si_13.5B₉ ribbon was observed around 10 MHz frequencies
