Аннотация:The superconducting phase transition in {\rm Nb/Cu_{0.41}Ni_{0.59}/Nb} trilayers, with superconducting (S) Nb and ferromagnetic (F) {\rm Cu_{0.41}Ni_{0.59}}, has been experimentally studied as function of the F-layer thickness by measuring the temperature dependence of the electrical resistance R(T). It is shown that the shape and the width of the R(T) curves depends on the {\rm Cu_{0.41}Ni_{0.59}} thickness, in particular in the regime where π-coupling between the S-layers can be expected. To explain the data we developed a qualitative model which makes the interconnection between the superconducting phase transition and the 0 to π transition in SFS structures more evident.
