Superconductivity in a Tl-Pb-Pr-Sr-Cu-O System

Superconductivity in the Tl-Pb-Ln-Sr-Cu-O (Ln=La, Pr, Nd) system has been found. Samples were synthesized by annealing of precursors, Pb-Ln-Sr-Cu-O ceramics, in Tl oxide vapor. In the case of Ln=Pr, electrical resistance vanished below 43 K, and the Meissner effect appeared below 46 K.
