摘要：

The temperature (T) dependence of the resistivity of Co/Cu superlattices having antiferromagnetic (AF) and ferromagnetic (F) interlayer exchange coupling was investigated. The results show that the resistivity versus temperature relationship exhibits a minimum for AF-coupled Co/Cu superlattices while that for F-coupled Co/Cu superlattices dose not. This minimum can be explained by the T dependences of the magnetoresistance (MR) and saturation resistivity, which behave as T(n) power laws for T dependence of MR at low temperatures. The power laws for T dependences of MR are related to the two-dimensional (2D) behavior due to the weak interlayer exchange coupling and to the T dependence of the magnetization.
