摘要：

The effect of the exchange energy variation in weakly ferromagnetic alloys on the superconducting resistive transition of superconductor/ferromagnet/superconductor (S/F/S) trilayers is studied. Critical temperature, Tc, and resistive transitions versus the F-layer thickness, dF, have been analyzed in Nb/Cu0.41Ni0.59/Nb and Nb/Pd0.81Ni0.19/Nb trilayers. We show that Tc(dF) dependence is sensitive to magnetic inhomogeneities in the F-layer for values of dF corresponding to thickness range where the π-superconducting state is established.
