本文研究了（Co_（90）Nb_（10）/Ta）（n）多层膜的静态和高频磁性。结果表明，只要将Ta中间层的厚度从8.0 nm减小到1.8 nm，面内单轴磁各向异性场就可以从12 Oe调节到520 Oe。结果，多层膜的谐振频率从1.4 GHz连续增加到6.5 GHz。通过对Δ M（H）曲线的研究发现，面内单轴各向异性场的变化归因于磁性层之间的层间相互作用。
In this work, the static and high frequency magnetic properties of (Co90Nb10/Ta)(n) multilayers have been investigated. The results show that the in-plane uniaxial magnetic anisotropy fields can be adjusted from 12 to 520 Oe only by decreasing the thickness of Ta interlayers from 8.0 to 1.8 nm. As a consequence, the resonance frequencies of the multilayers continuously increased from 1.4 to 6.5 GHz. It was found that the changes in the in-plane uniaxial anisotropy field are ascribed to the interlayer interactions among the magnetic layers by investigating the delta M(H) curves.
