Abstract
The pressure dependences of the superconducting transitions of the title materials have been studied under hydrostatic pressure up to Gpa. The midpoints of the resistive transitions were 92.2 K and 93.2 K for YBa2Cu3O7-y and GdBa2Cu3O7-y, respectively, and increased with increasing pressure at a rate of (5–6)×10-3 GPa-1. The critical current of GdBa2Cu3O7-y was two to three times as large as that of YBa2Cu3O7-y; both were enhanced by the application of pressure.Keywords
