Abstract

Careful characterization of (Y0.95Sr0.05)(Ba1.5Sr0.5)Cu3O7−δ and Y(Ba1.5Sr0.5)Cu3O7−δ ceramic samples has confirmed the simultaneous substitution of Sr for both Y and Ba in the YBa2Cu3O7 structure. The substitution at the Y site has a distinct effect on the superconducting properties of the material. The inter-grain transport properties of both samples in an external d.c. field are enhanced with respect to undoped YBa2Cu3O7 ceramics.
