Abstract
<jats:p>Effect of structure on oxygen diffusion <jats:italic>D</jats:italic><jats:sub>0</jats:sub> in two different structures of La<jats:sub>2</jats:sub>CuO<jats:sub>4</jats:sub>. Higher density of mobile defects in T-structure leads to higher <jats:italic>D</jats:italic><jats:sub>0</jats:sub>, but the lower activation energy for T′-structure is correlated with its lower migration energy.</jats:p>
