Abstract
The influence of the diameter reduction and annealing conditions on the magnetic properties and giant magnetoimpedance
(GMI) response of FINEMET wires with diameters from 50 μm down to 10 μm have been investigated. The results reveal
potential ways to improve the soft magnetic properties of nanocrystalline microwires, the permeability reaching a maximum
after annealing at 500˚C (5.3 105
) and the GMI response being maximum after annealing at 550˚C (248%), with a great
importance for future sensor applications based on these novel materials..
