      abstract     = {The dependence of the critical current density j(c) on the
                      ferromagnetic interlayer thickness d(F) was determined for
                      Nb/Al2O3/Cu/Ni/Nb Josephson tunnel junctions with
                      ferromagnetic Ni interlayer thicknesses from very thin films
                      (similar to 1 nm) upward and classified into F-layer
                      thickness regimes showing a dead magnetic layer, exchange,
                      exchange + anisotropy and total suppression of j(c). The
                      Josephson coupling changes from 0 to pi as function of d(F),
                      and-very close to the crossover thickness-as function of
                      temperature. The strong suppression of the supercurrent in
                      comparison to nonmagnetic Nb/Al2O3/Cu/Nb junctions indicated
                      that the insertion of a F layer leads to additional
                      interface scattering. The transport inside the dead magnetic
                      layer was in dirty limit. For the magnetically active regime
                      fitting with both the clean and the dirty limit theories was
                      carried out, indicating dirty limit condition, too. The
                      results were discussed in the framework of literature.},
