摘要：

We report magnetic susceptibility, electrical resistivity, and Hall-effect measurements on single crystals from the n-type high- Tc superconducting system Pr2-xCexCuO4-δ. Using an improved reduction technique, we find that bulk superconductivity can be established over the broad Ce concentration range 0.04≤x≤0.17. The new superconducting phase diagram and the systematics of the electronic transport properties resemble those observed in the overdoped concentration range of the p-type high- Tc superconductors. © 1995 The American Physical Society.
