Abstract
The mercury-based superconductor Hg-1223 with Pb substituted for Hg has a transition temperature (, the zero-resistance temperature, ; , the diamagnetic onset temperature, = 143 K) higher than that for pure Hg-1223 compound. The structure of this Pb-doped sample has been investigated via neutron powder diffraction. Some selected bond distances are compared to those of Pb-free Hg-1223 cuprate. The contents of Pb and oxygen have been refined. The estimated valence of copper is about 2.30, which is consistent with that for YBCO superconductor.
