Abstract

Ten new superconducting cuprate perovskites with Tcs above 77 K are reported. The highest Tc of the new group, and for any superconductor, is observed in Ba2Eu0.9Y0.1Cu3Ox which has a resistive midpoint of 94.5 K with a width of 0.7 K. Miessner effect and ac susceptibility measurements indicate bulk superconductivity in these materials. Each of these cuprates has a two-to-one ratio of divalent to trivalent ion on the A site of the perovskite-type structure.
