This paper presents superconducting properties and structural analysis of RBa{sub 2} (Cu{sub 1 {minus} x} Ag{sub x})O{sub 7} (with R = Y, Eu and Gd) ceramic compounds. Transition temperatures improve with a small amount of Ag. Results of powder X-ray diffraction indicate no detectable substitution of Ag into the RBa{sub 2}(Cu{sub 0.999}Ag{sub 0.001}){sub 3}O{sub 7} oxide system. The authors found that no superconductivity was observed above 10 K for RBa{sub 2}(Cu{sub 0.4} Ag{sub 0.6}){sub 3}O{sub 7} compounds. The superconductivity is discussed in relation to the results of X-ray diffraction study.
