Abstract
The longitudinal resistance,R xx , the Hall resistance,R xy , and the critical current density,j c , were measured for two Nb/Cu multilayers with different thickness of the Cu layers. The magnetic field was applied perpendicular to the layers. A peak-like anomaly ofR xy , accompanied by a sign reversal, is interpreted using a phenomenological model. The temperature dependence ofj c (T)=j c0 (1−T/T c0 )2/T 5/2 coincides with the theory of Aslamazov, D'yachkov, and Lempitskii.
