Pressure is an important research tool in understanding the nature of superconductivity and in the development of new superconducting materials. Experiments have been performed at NRL at pressures to 7 GPa on single crystals of Tl2Ba2CaCu2O8+δ, Tl2Ba2Ca2Cu3O10−γ, and NdBa2Cu3O7−δ. All three materials exhibit a positive dTc/dP which decreases with increasing pressure; in several instances, an extremium in Tc(P) is found. For Tl2Ba2Ca2Cu3O10−x, Tc was observed to increase from 116 K at atmospheric pressure, to a value as high as 131.8±0.5 K at 7 GPa. Measurements of Tc(P) on NdBa2Cu3O7−δ were found to be in conflict with an empirical prediction for this material. |
