Abstract: We investigated the superconducting proximity effect in both Nb(35 nm)/PdNi superconductor (S)-ferromagnet (F) bilayer and Nb–Nb(10 nm)/PdNi–Nb (S–SF–S) variable-thickness bridges (VTBs). In Nb(35 nm) PdNi(dF nm) SF bilayer, non-monotonic behavior of the superconducting transition temperature Tc was observed as a function of PdNi thickness, dF. This non-monotonic behavior of Tc can be interpreted from the view point of damped oscillatory superconducting order parameter induced in F-layer, and the effective exchange energy Eex extracted from the data was approximately 150 K. On the other hand, in VTBs, it was found that the superconducting critical current Ic was monotonically decreased with increasing dF.
