| dc.description | Utilizing AC susceptibility measurements the authors have investigated the inter and intragranular properties of selected bulk materials under hydrostatic pressures to 3.5 GPa. A single phase Tl<sub>2</sub>CaBa<sub>2</sub>Cu<sub>2</sub>O<sub>8</sub> sample with superconducting transition temperature T<sub>c</sub> approximately=107 K shows a clear maximum in T<sub>c</sub>(P) at approximately 2.2 GPa coupled with a nearly twofold increase to 3 GPa of the intergranular critical current density J<sub>cJ</sub> near T<sub>c</sub>. The second sample, a YBa<sub>2</sub>Cu<sub>4</sub>O<sub>8</sub> sinter, shows a large linear increase in T<sub>c</sub> with pressure (+5.5 K/GPa) as well as a fivefold increase J<sub>cJ</sub> to 3 GPa. Applying a critical state model, the authors find that T<sub>c</sub>(P) varies as lambda <sub>g</sub><sup>-2</sup>(P), where lambda <sub>g</sub> is the intragranular (London) penetration depth. |
