Ss. Yoon et al., Analysis of giant magneto-impedance in terms of anisotropy field in annealed amorphous Co66Fe4NiB14Si15 ribbons, J MAGN MAGN, 203, 1999, pp. 301-303
The magneto-impedance (MI) profiles of Co66Fe4NiB14Si15 amorphous ribbons c
hanged sensitively with the annealing temperature, reflecting the change in
anisotropy field, which determines the field dependence of transverse perm
eability. The effective anisotropy held, evaluated from these profiles, wer
e discussed in terms of the increase of magnetic softness and microstructur
al change due to the annealing. (C) 1999 Elsevier Science B.V. All rights r
