Notes:
Gold powder was mixed with YBa2Cu3O7−x superconductors for the purpose of increasing the critical current density (Jc). The critical transition temperature at zero resistance (Tzeroc) gradually decreased by the Au addition. However, the depression of Tzeroc was as low as 2 K for the YBa2Cu3O7−x -Au composite with Au mixing up to 40 wt.%. A maximum Jc of 307 A/cm2 was obtained for the Au 5-wt. % mixed composite. The Jc was about four times as high as that for YBa2Cu3O7−x without Au mixing. In addition to the Jc enhancement, the weak-link problem was appreciably improved by the Au addition.
