Superconductivity above 250K in Tl₁.₈Ba₂.₀Ca₂.₆Cu₃.₀O₁₀+δ high pressure
The pressure dependence of the superconducting transition temperature Tc(onset) of Tl₁.₈Ba₂.₀Ca₂.₆Cu₃.₀O₁₀+δ (Tl-2223) has been measured under quasi-hydrostatic pressure (QHP) up to 5.0 GPa. The Tc increases with increasing pressure at a relatively high rate and reaches a maximum at 255.4 K and pres...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The pressure dependence of the superconducting transition temperature Tc(onset) of Tl₁.₈Ba₂.₀Ca₂.₆Cu₃.₀O₁₀+δ (Tl-2223) has been measured under quasi-hydrostatic pressure (QHP) up to 5.0 GPa. The Tc increases with increasing pressure at a relatively high rate and reaches a maximum at 255.4 K and pressure of about 4.3 GPa. This is the highest Tc yet observed for any high-Tc superconductor. The total change in Tc from ambient condition (Tc=129K) to the high pressure applied can be greater than 126 K. The Tc above 200 K was replicated several times in our experiments. The site of the maximum of Tcn and the value of dTc/dP=1.7K/GPa (at P = 0) agree with previous results obtained by D. Tristan Jover et al. [1] and J. G. Lin et al. [2], respectively. |
