Hole dependence in (Hg, Re)-1201 compound

Abstract:

We analyze the influence of oxygen and Re content on the superconducting response of single phase Hy1-xRexBa2CuO4+δ (0< x <0.15) samples. The results of thermoelectric power and d.c. magnetization measurements let us to analyze the effect of both substitutions on Tc and the hole concentration (p). A comparison with previous reported Tc(p) data indicate that this relashionship differs from the common parabola followed by many other high-Tc materials and some features are remarkably independent of structural and chemical details. © 2004 Plenum Publishing Corporation.
