摘要：

The pressure dependence of the superconducting transition temperature T(c) of Tl2Ba2Ca2Cu3O10+x (Tl-2223) has been measured under pressures up to 13 GPa (130 kbar). At 4.2 GPa a maximum is observed with a T(c) of 133 K. This is the highest T(c) yet observed for any high-T(c) superconductor with the exception of the recently discovered mercury-based compound Hg-Ba2Ca2Cu3O8+x (Hg-1223). Because of some structural differences between Tl-2223 and Hg-1223, a slightly higher maximum T(c) is predicted for Hg-1223. Both T(c) and its pressure dependence are discussed on the basis of a simple charge-transfer model.
