We observe a sign reversal of the Hall resistivity in the mixed state of the n-type superconductor Ndl.s5Ceo.15CuO4. ~. Such all anomaly, which has also been observed earlier in the p-type oxide superconductors, has been widely attributed to thermoelectric effects, pinning effects, or else to compli
## Magnetoresistivity measurements above r, ( zz 14 K) on a superconducting Sml.g5Ce,,,5Cu0., single crystal have been performed. In spite of the cerium doping, the low-temperature normal state Hall coefftcient is found to be positive, whereas at high temperature (T> 80 K) it becomes negative. The
