摘要：

In order to develop new metal stabilizers with a low heat transport capacity for Bi-based oxide superconducting power current leads, the thermal conductivity and electrical resistivity of Ag-Au and Ag-Cu alloy tapes heat treated in air were investigated from 15 to 260 K. The thermal conductivity of Ag-Au alloy tapes decreased drastically at low temperatures with increasing Au content after the heat treatment necessary to realize the superconducting wire. By contrast, the thermal conductivity of Ag-Cu alloy tapes hardly decreased because of oxidation of Cu during the heat treatment.
