• 論文の詳細を見る

• We have measured the resistivity ρ of the Au-Bi_2Sr_<1.8>Ca_<1.2>Cu_2O_y composite system with Au volume fraction p_<Au> ranging from 0.00 to 1.00. We find, for the samples with p_<Au>≤0.4, that the addition of Au does not disturb the superconducting transition temperature of Bi_2Sr_<1.8>Ca_<1.2>Cu_2O_y. For the samples with p_<Au>≥0.6, no zero-resistivity state is observed. The variation of ρ(300 K) with p_<Au> indicates a three-dimensional percolating Au matrix occurring at p_<Au>≈0.18.
