| Abstract: | Abstract The electrical resistance of dense YBa2Cu3Ox and YBa2Cu4Oy produced by hot isostatic pressing has been measured vs. T and p. At 295 K we find d (ln R)/dp ? -0.12 and -0.09 GPa?1, respectively, with no systematic dependence on initial density. For 1-2-4, dTC/dp ? 5.1 K/GPa, which is ten times that of 1-2-3. |
