Popis: Several members of a new family of (Hg,Tl) (Ba,Sr) Ca n −2 Cu n −2 O x high-temperature superconductors have been synthesized at elevated pressures and 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 appears to stabilize several of the Tl compounds, including a double-layer Tl/Sr system in a manner similar to the role that Pb plays in the Tl/Sr and Bi/Sr systems.
