Abstract

Isothermal resistance measurements were used to monitor oxygen indiffusion and out-diffusion in single crystal YBa2Cu3O7−δ from 600-780°C. Measurements on single crystals reveal that oxygen out-diffusion is intrinsically faster than in-diffusion, which is contrary to the rates observed in other studies for polycrystalline ceramics. Oxygen out-diffusion measurements suggest two different mechanisms, one above an4 one below ˜680°C,which have activation energies of 1.57±0.06eV and 1.00±0.04eV, respectively. Calculation of relaxation times for oxygen in-diffusion into initially tetragonal YBa2Cu3O7−δ suggest a single mechanism from 600-780°C with an activation energy of 1.16±0.06eV.
