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, T <Subscript> c </Subscript>, and resistive transitions versus the F-layer thickness, d <Subscript> F </Subscript>, have been...</subscript></subscript>
