Abstract:
Effect of annealing on the soft magnetic properties of Fe73.5Si13.5B9Nb3Au1 amorphous ribbon
has been investigated by means of structure examination, magnetoimpedance ratio (MIR) and incremental
permeability ratio (PR) spectra measured in the frequency range of 1-10 MHz at a fixed current of 10 mA Xray
diffraction analysis showed that the as-cast sample was amorphous and it became nanocrystalline under
a proper heat treatment. When annealing amorphous alloy at 530 ?C for 30, 60, 90 min, soft magnetic
properties have been improved drastically. Among the samples investigated, the sample annealed at 530 ?C
for 90 min showed the softest magnetic behavior. The MIR and PR curves revealed the desirable changes in
anisotropy field depending upon annealing. ?? 2006 Elsevier B.V. All rights reserved.
