Thermal co-evaporation of neodymium, cerium and copper in an oxygen atmosphere produces tl~i~, films of the 20 K, n-type superconductor, Nd2\_xCexCuO4\_6. The resistive transition is sharp ( 0.9 K, 90o/o -10% ) and complete at 22 K in ambient magnetic field. The resistive transition broadens if a ma

## Magnetic susceptibility and magnetization data are presented for the Nd,\_,Ce,CuO,\_, system. The Nd local moments are seen to be crucial in interpreting the magnetic response. Evidence for a pervasive diamagnetic component (onsetting near 24 K) in the low field response, which is sharply maxi
