Description

In the Eu(Gd)SrxBa2-xCu3Oy systems, EuSrBaCu3Oy and GdSrBaCu3Oy for y=6.94 were found to the bulk superconductors with no long-range order of the Cu-O chain. The Tc monotonously decreases with decreasing y and the superconductivity disappears in the vicinity of y=6.65. The disappearance of superconductivity in the range of relatively high hole concentration is explained in terms of the absence of self-doping in which hole is created in the CuO2 plane and consequently in the relation of Tc versus y the decrease of oxygen content results in a reduction of the hole concentration in the CuO2 plane.
