Pressure dependence of the transition temperature r, in the electron-doped superconductor Nd,.85Ce,,,5Cu04 is considered to be anomalous since T, hardly varies with pressure, in contrast to the case of the hole-doped superconductors where there is initially an increase in T, with pressure reaching a
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
The fluorine-doped n-type superconductors Ndl.s5Ce0.15CuO4\_x\_yFy (nominal composition) are synthesized with CuF z as one of the reactants. Especially, it is found that the superconductivity of Nd1.85Ce0.15CuO4\_~ is improved with Tc °n= 27 K, T ° = 15.5 K when CuF 2 is taken as a source of atmosph
