Abstract

Abstract: The structure and properties of YBa₂Cu₃O_7-y:Ag_x superconductor have been studied. Thesystem showed lower normal state resistivity and better ductility.XRD analysis showed thatthe system remains orthorhombic structure when the content of silver x<2.0.Increase of Agdid not change the a and b axes but substantially expanded in the c axis about 0.33% atx=1.5. This indicates that the silver has partly enter into the lattice cell of 123 phase.YBa₂Cu₃O_7-y:Ag_x exhibits fine grains and net framework improving the weak-link in it inSEM. The critical current density is enhanced from 50A/cm² to 572A/cm².

Key words: YBa₂Cu₃O_7-y Ag_x, superconductor, silver
