Creep and diffusion in high $\mathit{T}_\mathrm{c}$ superconductors
Overview & Synopsis
Data from steady-state creep and tracer diffusion tests are presented for the high-Tc, superconductors YBa2Cu3Ox, and Bi2Sri1.7CaCu2Oy Both compounds exhibit oxygen nonstoichiometry and possess orthorhombic, layered perovskite crystal structures in which Cu occupies the B sites and the other cations occupy the A sites. For each, the A-site cations diffuse most slowly. For every species that has been measured, diffusion is much faster in the ab-plane than in the c-direction. At low stresses, both superconductors deform by diffusional creep with the ratecontrolling species being a A-site cation in YBa2Cu3Ox.
