研究了Ni-Co/Cu和Co-Fe/Cu多层膜的层间交换耦合巨磁电阻效应的组分依赖性。通过磁控溅射在玻璃衬底上制备样品。它们具有平行于生长方向的fcc（111）择优取向。MR比和饱和场都被观察到振荡的Cu厚度的函数在这两个系统的研究。的MR比和饱和场的峰值作为磁性层组合物的函数表现出最大值附近的Co的电子数，定性与理论计算的基础上的安德森模型。
The composition dependence of the giant magnetoresistance due to the interlayer exchange coupling of Ni-Co/Cu and Co-Fe/Cu multilayer films was studied. Samples were prepared by magnetron sputtering on a glass substrate. They had an fcc (111) preferred orientation parallel to the growth direction. Both the MR ratio and the saturation field were observed to oscillate as functions of the Cu thickness in both systems studied. The peak values of the MR ratio and saturation field as functions of the magnetic layer composition exhibited maxima near the electron number of Co, in qualitative agreement with theoretical calculations based on the Anderson model.
