| The ferroelectric relaxor Pb(Sc0.5Ta0.5)O3-superconductor YBa2Cu3O7-δ 50% in weight composite exhibits the onset critical temperature Tc=95 K. High pressure studies yield the factor dTc/dp of 1.0 K/GPa, close to the value observed for a pure YBa2Cu3O7-δ compound. The microwave absorption studies show the significant role of the intergrain weak links. |
