Abstract

A two-dimensional theoretical model of stress-induced point-defect relaxation in a layered structure is presented, with a detailed discussion of the special case of

{YBa}_{2}

{Cu}_{3}

O_{6 + x}

. The experimental results of oxygen relaxation in

{YBa}_{2}

{Cu}_{3}

O_{6 + x}

can be explained qualitatively by this model.
