研究了Fe75.5Cu1Nb3Si13.5B7非晶薄带/Fe 80 Ga 20薄膜复合材料的优化巨磁阻抗效应。以FeCuNbSiB非晶薄带为衬底，采用离子束溅射法在其单面或双面沉积磁致伸缩FeGa薄膜。与未覆盖FeGa层的FeCuNbSiB非晶薄带的GMI曲线相比，覆盖FeGa层后（从4%增加到16%），非晶薄带的GMI效应得到了明显改善。此外，在一定频率下，当带的一侧覆盖FeGa薄膜时，GMI比随FeGa薄膜厚度的增加而减小;而当带的两侧覆盖FeGa薄膜时，GMI比随FeGa薄膜厚度的增加而增加。这主要是由于在纵向磁场作用下，磁致伸缩效应引起的应变各向异性引起的。
Optimized giant magnetoimpedance effect of Fe75.5Cu1Nb3Si13.5B7amorphous ribbon/Fe80Ga20film composites has been investigated. FeCuNbSiB amorphous ribbons as the substrates are commercially available, magnetostrictive FeGa films are deposited on one or both sides of the ribbons by ion-beam sputtering. Compared with the GMI curves without FeGa layer, the GMI effect of FeCuNbSiB amorphous ribbon has been obviously improved with FeGa film covered (from 4% to 16%). Moreover, the details exhibit an interesting phenomenon: at a certain frequency, when the FeGa film covered on one side of the ribbon, the GMI ratio decreases with the thickness of the FeGa film; however, when the FeGa films covered on both sides of the ribbon, the GMI ratio increases with the thickness of the FeGa film. We mainly attribute the reason to strain-induced anisotropy, which is induced by magnetostrictive effect under a longitudinal applied magnetic field.
