Abstract
We have observed a nonmonotonic behavior of the superconducting critical temperature Tc 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 π phase in the case of layered superconducting systems with weak magnetic coupling, where the phase φ of the superconducting order parameter can vary in the range 0<φ<π between adjacent superconducting layers.
