Using Nd 2\_xCe~CuO4 ,. films, the temperature dependence of electrical resistivity in the mixed state has been measured as a function of magnetic field and its direction from the basal plane. These data have been analyzed by a phenomenological theory on the basis of the thermal fluctuations of the

ystals of the N-type superconducting Nd2\_~CexCuO4\_~. system have been grown by a self-flux technique. In this method, excess Ce is required to obtain single crystals with optimal superconducting properties. Crystals grown by this technique show superconducting transition temperatures with onsets o
## Superconductivity in the Nd \V Ce V CuO \W (NCCO) system can be obtained in a narrow range of the cationic and anionic stoichiometry. One possibility to enlarge this range is lowering oxygen concentration with preservation of the ¹ structure. The surface morphology of Nd Ce CuO \W after heat tr
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
