✦ Synopsis

Superconducting transition onset around 30-31 K was reported for the repeated-vacuum/Ar-annealed and liquid-nitrogen-quenched sample of the high T c electron superconductor Nd1.85CeO.15Cu04_0 (0 = 0.07(2)).

Vortex lattice melting near T c was observed for this oxygen-reduced superconductor. Low field « 5 kG) magnetic phase diagram showed an irreversibility line (de-Almeida-Thouless line) H*(T) which was found to 5/3 vary as (I-T/T c ) .

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
