Abstract

Bi₂O₃ is added to ceramic YBa₂Cu ₃O_x by powder mixing and 'grain coating' respectively. As the result of the transport measurements, T_c is found to be improved by Bi₂O₃ addition. In particular, introduction of Bi ₂O₃ by use of the 'grain coating' process, which the authors propose as a method of obtaining a thin and even intergrain distribution, produces a considerable enhancement in J_c. The optimum coating thickness falls in the vicinity of the coherence length of the oxide superconductor.
