摘要：

A classification of p-type superconductors is proposed. According to this classification, PbPr2.4Sr1.6Cu2.6Oy ceramic was designed and synthesized as a ceramic having a new crystal structure. This ceramic has a tetragonal symmetry (a=0.388 nm, c=2.914 nm) and consists of three blocks which are a (Pb/Cu)-O single layer, a Cu-O5 pyramid and a fluorite-type Pr2-O2 layer. It is expected to be a mother material of superconductors. © 1990.
