Abstract

A new high‐T_c superconducting material based on the title system has been synthesized at one atmosphere of oxygen. X‐ray powder diffraction as well as energy dispersive spectrometric analyses shwo a phase with the chemical composition (In_0.05PB_0.70Cu_0.25) (Ca_0.05Y_0.05)Sr₂Cu₂O_y, which is isostructural with TlCaBa₂Cu₂O₇, to be responsible for the superconductivity.
