| Abstract: | We investigate Co/Nb multilayers to explore the spontaneous pi-phase shift between the superconducting (SC) layers, which is attributed for causing the non-monotonic change of the SC transition temperature (T-c) with the ferromagnetic (FM) layer thickness (t(FM)) in several FM/SC multilayered systems. The issue of interfacial roughness is also explored by growing Co/Nb multilayers at various sputtering pressures. Transport measurements show a non-monotonic dependence of T-c on t(FM), and this dependence is insensitive to the structural variation present in the samples, as measured by X-ray scattering.
