      abstract     = {Oxygen interstitials and vacancies play a key role in
                      modulating the microstructure and properties of
                      nonstoichiometric oxide systems, such as those used for
                      superconductors and multiferroics. Key to understanding the
                      tuning mechanisms resulting from oxygen doping is a
                      knowledge of the precise positions of these lattice defects,
                      and of the interaction both between these defects and with
                      many order parameters. Here, we report how such information
                      can, for the first time, be obtained from a sample of
                      LuFe2O4.22 using a range of techniques including advanced
                      electron microscopy, atomic-resolution spectroscopy, and
                      density functional theory calculations. The results provide
                      quantitative atomic details of the crystal unit cell,
                      together with a description of the ferroelastic,
                      ferroelectric, and ferromagnetic order parameters. We
                      elucidate also the interaction between these order
                      parameters and the positions of the oxygen interstitials in
                      the oxygen-enriched sample. The comprehensive analysis of
                      oxygen interstitial ordering provides insights into
                      understanding the coupling among different degrees of
                      freedom in rare earth ferrites and demonstrates that oxygen
                      content regulation is a powerful tool for tuning the
                      microstructure and properties for this class of quantum
                      material.},
