Description

The authors have studied various compositions of the Ysub(3-x)Basub(3+x)Cu6O14 and report the isolation of the pure oxide phase responsible for high Tsub(c) superconductivity. The oxide has composition Ysub(0.33)Basub(0.67)CuOsub(2.33+-delta), with an oxygen defect perovskite structure. The pure oxide shows the onset of superconductivity at 120 K, attaining zero resistance at 87 K. It also exhibits the highest Meissner effect of all the high-Tsub(c) oxide superconductors. (author)
