Abstract:

The effect of ferromagnetic layer inhomogeneity on the superconducting resistive transition in Superconductor/Ferromagnet/Superconductor (S/F/S) trilayers is studied. The critical temperature, T_c, and the resistive transition shape versus the F layer thickness, d_F, in Nb/Cu_0.41Ni_0.59/Nb and Nb/Pd_0.81Ni_0.19/Nb trilayers were analyzed. It is shown that the T_c(d_F) dependence is sensitive to the Ni concentration variation along the F layer for thickness of d_F corresponding to the π-superconducting state and to the 0-π crossover thickness.
