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.},
