Abstract

Amorphous Fe73.5Cu1.0Nb3.0Si13.5B9 microwires are prepared by the Taylor-Ulitovsky method. Then, the as-prepared microwires are annealed by cuurent annealing. The best performance microwires are obtained at annealing current density of 4.2×107 A/m2 because of the suitable volume ratio between nanocrystalline and amorphous phases. Influence of length on giant magnetoimpedance effect and magnetic properties for microwires is then investigated. The results show that anisotropy field increases and the GMI ratio descreases with decreased length of the wire. Demagnetizing field model gives a reasonable explanation.
