      abstract     = {We report on O-18 tracer diffusion experiments and model
                      calculations for the study of cation vacancy migration in
                      oxide crystals. The model takes advantage of the
                      electrostatic coupling forces between anion and cation
                      defects that allow the evolution of the cation vacancy
                      profile to be observed by anion tracer experiments. Applied
                      to SrTiO3, the ambipolar diffusion of strontium vacancies
                      with H-A = 3.5 eV was found to be the dominant
                      reequilibration mechanism of the cation sublattice. This
                      result is in contrast to earlier studies proposing the
                      formation of SrO intergrowth phases.},
