Doping dependence of the critical current in Bi2Sr2CaCu2Oy

Muntaser Naamneh, Juan Carlos Campuzano, Amit Kanigel

The doping dependence of the critical current density, $J_c$, was measured in a series of high quality c-axis oriented $\mathrm{B}{\mathrm{i}}_2\mathrm{S}{\mathrm{r}}_2\mathrm{CaC}{\mathrm{u}}_2{\mathrm{O}}_{8+\delta }$ thin films. For each doping l…
