The longitudinal resistance, R(xx), the Hall resistance, R(xy), and th
e critical current density, j(c), were measured for two Nb/Cu multilay
ers with different thickness of the Cu layers. The magnetic field was
applied perpendicular to interpreted using a phenomenological model. T
he temperature dependence of j(c)(T)=j(c0)(1 - T/T-c0)(2)/T-5/2 coinci
des with the theory of Aslamazov, D'yachkou, and Lempitskii.
