Bulk superconductivity up to 60 K in the In-Pb-Ca-Y-Sr-Cu-O system



A new high-Tc 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 (In0.05PB0.70Cu0.25) (Ca0.05Y0.05)Sr2Cu2Oy, which is isostructural with TlCaBa2Cu2O7, to be responsible for the superconductivity.
