Development of high critical current density in multifilamentary round-wire Bi2Sr2CaCu2O8+x by strong overdoping

T. Shen, J. Jiang, A. Yamamoto +4

Bi2Sr2CaCu2O8+x is the only cuprate superconductor that can be made into a round-wire conductor form with a high enough critical current density Jc for applications. Here we show t…
