Amorphous Fe73.5Cu1Nb3Si13.5B9 microwires were prepared by glasscoated melt spinning technique. Nanocrystalline samples were obtained by annealing the amorphous wires at 570 ℃.The diameter of the microwires varied between 16~50 μm.The relationship between giant magnetoimpedance effect and the metallic core diameter was investigated. The results showed that the GMI ratios first increase then decrease with the increase of metallic core diameter. The highest magnetoimpedance ratio of 251% is obtained in the nanocrystalline microwire with 30 μm in diameter.
