Title: EFFECT OF OXYGEN STOICHIOMETRY VARIATION ON T(C) IN ND1.85CE0.15CUO4-DELTA

Abstract: The oxygen vacancy parameter, delta, in electron-doped superconducting Nd1.85Ce0.15CuO4-delta, has been varied by changing the sample-processing conditions. A T(c)-onset value of 19 K was obtained by quenching alone. T(c) onset as high as 24 K, T(c)(R = 0) = 17 K and DELTAT(90%-10%) = 3 K have been achieved for delta = 0.05 in argon-annealed single-phase Nd1.85Ce0.15CuO4-delta samples.
