Abstract
Proximity effect in Nb∕Pd0.86Ni0.14, Nb∕Cu0.46Ni0.54, and Nb∕Cu0.42Ni0.58 bilayers has been studied in the presence of an external magnetic field. Upper critical field measurements, performed in parallel configuration, reveal a shift of the two-dimensional–three-dimensional crossover temperature, which we relate to the different interface transparencies of the three analyzed systems.
