Abstract

We have measured the electrical resistivity, thermoelectric power, magnetic susceptibility, Hall coefficient and upper critical field near T_c in EuBa₂Cu₃O_x, where 6.09<x<7.0. These data suggest a Mott-Hubbard-like transition near a critical oxygen concentration x_c∼6.4-6.5. Our results, combined with those reported elsewhere, show a striking similarity between the addition of oxygen to EuBa₂Cu₃O₆ and the substitution of divalent atoms M for La in La_2-yM_yCuO₄. We suggest that superconductivity in both systems is associated with the Cu-O planes and is driven electronically.
