Abstract
The normal-state Hall effect of Nb/Cu multilayers is negative in contr ast to the positive Hall effect in Nb films. In the mixed state there is no sign reversal of the Hall voltage but a temperature and magnetic field broadening of the Hall resistance, R(xy), which is correlated w ith the broadening of the sheet resistance, R(xx). The temperature sca n of R(xy) shows a peak-like anomaly. A model for the normal-state Hal l effect in mutilayers is proposed.
