For these junctions a transition from 0- to \\pi-coupling is observed for a thickness d_F ~ 6 nm of the ferromagnetic Pd_{0.82}Ni_{0.18} interlayer. The magnetic field dependence of the \\pi-coupled junctions demonstrates good spatial homogeneity of the tunneling barrier and ferromagnetic interlayer.
