Notes:
A primarily single phase compound of composition (Tl0.5Pb0.5)Sr2(Eu2−xCex)Cu2O9 (where x ranges from (very-much-less-than)0.1 to 0.17) has been synthesized in the so-called 1222 structure. Bulk superconductivity near 40 K is induced via oxygen doping in 100 bar of oxygen at 550 °C. The material has been structurally characterized by diffraction and high-resolution lattice imaging techniques. The lattice images reveal the presence of some intergrowths of a 1212 structure nonsuperconducting (Tl0.5Pb0.5)Sr2EuCu2O7 phase in the bulk 1222 structure of the parent compound and indications of periodicity that suggest the possible existence of a new, composite structure 2434 phase.
