Transport and magnetic properties of the T′-phase Nd2-xCexCuO4 system have been studied to investigate the occurrence of superconductivity by electron doping. The lattice constants and susceptibility of the system are reasonably interpreted in terms of all the Ce ions being tetravalent. The resistivity decreases by more than three orders of magnitude with Ce doping up to x=0.2. The measurements of thermopower confirm that the resistivity decrease arises from the increase of electron carriers supplied by the Ce4+ ions. Anomalous resistivity decreases are observed below 11 K, suggesting the occurrence of superconductivity in this system.
