| 摘 要： | 传统巨磁阻抗材料重量大、成本高、功能单一.将软磁合金材料与新型碳材料(碳纤维、石墨烯)进行复合,保证巨磁阻抗效应高灵敏度的同时,兼顾碳材料的诸多优势.针对两类典型碳材料,分别研究其与Fe基软磁合金组成的复合材料的结构、静态磁性、巨磁阻抗特性,并将该类新型材料的巨磁阻抗性能与传统材料进行对比.结果发现:软磁合金包裹的碳纤维丝的巨磁阻抗效应优异;石墨/Fe Ni合金组成的层状结构复合材料能够在低频下获得优异的巨磁阻抗性能.

| Abstract: | In order to solve some disadvantages (heavy,expensive and functionless) of traditional giant magnetoimpedance materials,enhanced magnetoimpedance effect has been investigated in carbon-based composite materials.Preprocessed carbon fibers covered by soft magnetic alloys show a good GMI characters.Graphene papers were synthesized in large quantities using a modified chemical approach.Soft magnetic FeNi alloy covered the top and bottom surfaces of graphene paper by electrochemical deposition and magnetron sputtering.Especially,the stratified FeNi/graphene/FeNi composite exhibited an enhanced magnetoimpedance effect. |
