Abstract
Although it has been demonstrated that metal additions to superconducting oxides can have a dramatic effect on superconductivity (as evidenced by variations in the resistancetemperature (R-T) signature), it is unclear where the metal additions go in the structure and what mechanism or mechanisms control the observed variations in superconductivity.Recent observations of explosively fabricated bulk YBa2Cu3O7 superconductors and sintered, shock-loaded YBa2Cu3O7 have indicated systematic degradation in the R-T signatures following shock-wave loading which increases with increasing peak shock pressure. However, silver additions to the Y-Ba-Cu-0 are observed to decrease this degradation. As illustrated in Fig. 1, the normal-state resistance becomes more metallic and the superconducting transition width decreases with increasing silver additions to sintered Y-Ba-Cu-O following shock loading at 3GPa peak pressure in a gas gun.
