Abstract

A new homologous series of superconducting cuprates containing a mercury-based bilayer has been synthesized using a high-pressure, high-temperature technique. It is found that Tl doping stabilizes a bilayer block with the rock-salt structure i.e. (Hg_1-xTl_x)₂-O₂. (Hg_1-xTl_x)₂Ba₂Ca₂Cu₃O_y and (Hg_1-xTl_x)₂Ba₂Ca₃Cu₄O_y as-prepared samples with analyzed Tl contents of approximately 0.4 exhibited bulk superconductivity below 45 K and 114 K, respectively.
