Abstract

Single crystals of Pr_2-xCe_xCuO₄ were grown using the CuO flux method. Large crystals in which the Ce distribution was homogeneous 50Ø×3 mm³ and 10×10×0.1 mm³, respectively. A small but high quality reduced Pr_1.84Ce_0.16CuO₄ crystals show superconductivity with a T_c of 18 K and a transition width of 1.5 K. We have examined the effects of Pt contamination from the Pt crucible. Only a 1% substitution of Pt for Cu eliminates the superconductivity entirely. Pt suppresses T_c more quickly in the Pr_2-xCe_x CuO₄ system than in the La_2-xSr_xCuO₄ system, where a Pt substitution of 2% eliminates the superconductivity.
