Abstract

High T_c superconductors, YBa₂(Ag_xCu_1-x)₃O_9-y with composition of 0≦x≦0.6 were prepared by a ceramic technique, and the compositional change of T_c was examined. Samples with nominal compositions of x<0.4, expecially YBa₂(Ag_0.1Cu_0.9)₃O_9-y and YBa₂(Ag_0.2Cu_0.8)₃O_9-yshow sharp superconducting transitions with widths as narrow as about 1 K or less. The superconductivity is discussed in relation to the results of X-ray diffraction study.
