Abstract
We have observed a nonmonotonic behavior of the superconducting critical temperature versus the CuMn layer thickness in multilayers of Nb/CuMn with fixed Nb layer thickness (∼250 Å). The results have been interpreted assuming the presence of the phase in the case of layered superconducting systems with weak magnetic coupling, where the phase of the superconducting order parameter can vary in the range between adjacent superconducting layers.
