通过巨磁阻抗（GMI）的变化研究了退火和离子辐照对非晶Co66Fe4B15Si15合金磁性能的影响。一般来说，淬火非晶样品和离子辐照样品之间的 GMI 曲线的大小和形状存在差异。结果表明，离子辐照对淬火样品磁性能的影响相当大，并且表现出离子剂量的依赖性。但是，在 380°C 退火的样品的 GMI 大小中观察到由离子辐照引起的急剧下降和离子剂量依赖性，由于超软磁材料的存在，该样品具有 GMI 最大值。
The effects of annealing and ion-irradiation on the magnetic properties of amorphous Co66Fe4B15Si15 alloys have been investigated by means of the changes of the giant magnetoimpedance (GMI). In general, there are differences in magnitude and shape of the GMI curves between as-quenched amorphous and ion-irradiated samples. The results indicate that the effects of ion irradiation on the magnetic properties of the as-quenched sample are quite large and show the dependence for ion dose. But a drastic decrease and ion-dose dependence, caused by ion-irradiation, is observed in the magnitude of the GMI of the sample annealed at 380°C, which has a maximum value of the GMI due to the presence of ultra-soft magnetic materials.
