摘要: Superconducting aluminum films show deviations from the mean field theory prediction of temperature dependence equilibrium order parameter close toT c . We that these can be explained by intrinsic variations inT grain to grain. When coherence length is larger than size, will occur over a much smaller interval because proximity effect.
