In this study, resonance enhancement of Giant MagnetoImpedance effect in Febased glasscoated microwires was investigated. A new method was adopted by sputtering a copper layer in the outside of the Febased glasscoated wires. A capacitance was formed between the ferromagnetic core and outer copper layer, where the glass insulator works as dielectric layer. Therefore, the composite wire constructs a LC resonance circuit by itself, resulting in an increase of GMI ratio from 250% to 330%. Meanwhile, the influence of resonance frequency on the GMI effect was discussed.
