中文摘要：
通过一种新的方法，直接在Fe基玻璃包裹丝外溅射一层铜.研究发现，玻璃绝缘层在复合结构丝中充当电介质的作用，内芯层与外层铜耦合形成附加电容，从而使复合丝形成LC回路，其巨磁阻抗效应从原先的250%增强到330%.通过改变外铜层长度，研究了共振频率对巨磁阻抗效应的影响.
英文摘要：
In this study, resonance enhancement of Giant Magneto-Impedance effect in Fe-based glass-coated microwires was investigated. A new method was adopted by sputtering a copper layer in the outside of the Fe-based glass-coated wires. A capacitance was formed between the ferromagnetic core and outer copper layer, where the glass insulator works as dielectric layer. There fore, 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.
