Abstract

The superconducting transition temperature T_c and the position lifetime τ of YBa₂Cu₃O_6.7, YBa₂Cu₃O₇, Y₂Ba₄Cu₇O₁₅ and YBa₂Cu₄O₈ have been determined under high pressures. The results demonstrate that all evolve from the same origin: two CuO₅-pyramid layers with different transfers of electrons to their vicinity, which give rise to different T_c's at ambient pressure. This is consistent with our recent conjecture that all known cuprate high temperature superconductors are mere modifications of the 214 and 123 phases.
