SUPERCONDUCTIVITY IN THE NEW HIGH-TC SUPERCONDUCTORS RBa2Cu3O9-y(R=Y, Nd, Sm, Eu, Gd, Dy, Er, Tm, Yb)

Abstract
Superconductivities in the 90K range as measured by resistance and magnetic susceptibility are reported for RBa2Cu3O9-y(R=Y, Nd, Sm, Eu, Gd, Dy, Er, Tm, Yb) having the orthorhornbic perovskite structure. Unstable resistance drop above 100K has been found in ErBCO, probably associated with interfacial superconductivity.
