Abstract

• The onset of superconductivity at 140 K has been observed in the high Tc Y-Ba-Cu-O system in samples consisting of 90% by volume of a single-phase oxide of average cation ratio Y:Ba:Cu���1:2:3. A sharp superconducting transition in the resistivity has been measured, where T c0=140 K, Tc=93.2 K, ��Tc=0.5 K, and "zero resistance" was observed at 92.0 K. Transmission electron microscopy and energy dispersive spectroscopy measurements revealed that the superconducting phase consisted of a large number of microcrystallites of ���0.5 ��m size and that these contained a very high defect microtwinned/faulted structure.
