Abstract
Several members of a new family of (Hg,Tl) (Ba,Sr)Can-2CunOx high-temp erature superconductors have been synthesized at elevated pressures an d temperatures. These compounds, which are analogs to the Hg-Ba-Ca and Tl-Ba-Ca layered cuprates, are multi-phased and have superconducting- transition temperatures which exceed 100 K. Incorporation of Hg appear s to stabilize several of the Tl compounds, including a double-layer T l/Sr system in a manner similar to the role that Pb plays in the Tl/Sr and Bi/Sr systems.
