Abstract
We report the observation of oscillations in the superconducting transition temperature Tc of Nb/Gd/Nb trilayers as the Gd layer thickness dGd is varied. The Tc minimum occurs at dGd≈13 Å. The results are consistent with our previous study of Nb/Gd multilayers and are in support of the theoretical prediction of a π-phase junction in superconductor/ferromagnet/superconductor systems.
