Abstract
Measurements of 2RbA, twice the boundary residual resistance times the cross-sectional area, for superconducting/ferromagnetic (S/F) boundaries in sputtered sandwiches yield values (in f Omega m2) of (6.1+or-0.3) for Nb/Co, (4.8+or-0.6) for Nb/Ni and (12.4+or-0.7) for NbTi/Co. These values are similar to those previously reported for superconducting/normal (S/N) boundaries in foil-based sandwiches, and smaller than predicted by the standard model.
