Description

We have determined the in-plane diffusion coefficient for nonstoichiometric oxygen in single crystals of Bi2Sr2CaCu2O8+δ (Bi-2212). This was done by measuring the superconducting diamagnetic transition of the crystals by AC susceptometry, following repeated annealing of the crystals at a range of temperatures. We find that the chemical diffusion coefficient for oxygen in Bi-2212 is well described by Dab*=(1.5-0.7+1.4)x10-3exp[-(1.23±0.06)eV/kBT]m2/s
