The present paper reviews oxygen diffusion data in high T/sub c/ superconductors. The model of defect interactions in La/sub 2-x/Sr/sub x/CuO/sub 4/, obtained from oxygen tracer diffusion measurements combined with positron annihilation results, is reviewed. Recent oxygen tracer diffusion measurements in polycrystalline YBa/sub 2/Cu/sub 3/O/sub 7-delta/ are presented. These results are discussed in the framework of the theory of Bakker et al. Chemical diffusion coefficients are reviewed and compared with the tracer values. 28 refs., 9 figs., 1 tab.
