SUPERCONDUCTOR

摘要

PURPOSE:To provide a new structure Pb oxide superconductor having a higher critical temperature than those of conventional Pb oxide superconductors by synthesizing a structure in which three CuO2 surfaces are disposed in a Perovskite type layer. CONSTITUTION:In a crystal structure, CuO5 pyramids 11 in a Perovskite type block layer 15 are faced to each other through a CuO2 surface 13 and A elements 14 in single atom layers on both the sides.
