Abstract
The pressure dependence of T-c in high-temperature superconductors is exper imentally found to be influenced not only by a pressure-induced increase in charge carrier density but also by intrisic effects. The influence of both contributions was systematically investigated in Tl0.5Pb0.5Sr2Ca1-xYxCu2O7 . The behavior of superconductors with three or four CuO2-layers is further complicated by the inequivalence of the inner and outer CuO2-layers. High- pressure experiments up to 46 GPa are analyzed in view of the above, (C) 19 99 Elsevier Science B.V. All rights reserved.
