      abstract     = {Iron oxide nanoparticles find a wide variety of
                      applications, including targeted drug delivery and
                      hyperthermia in advanced cancer treatment methods. An
                      important property of these particles is their maximum net
                      magnetization, which has been repeatedly reported to be
                      drastically lower than the bulk reference value. Previous
                      studies have shown that planar lattice defects known as
                      antiphase boundaries (APBs) have an important influence on
                      the particle magnetization. The influence of APBs on the
                      atomic spin structure of nanoparticles with the γ-Fe2O3
                      composition is examined via Monte Carlo simulations,
                      explicitly considering dipole–dipole interactions between
                      the magnetic moments that have previously only been
                      approximated. For a single APB passing through the particle
                      centre, a reduction in the magnetization of $3.9\%$ (for
                      9 nm particles) to $7.9\%$ (for 5 nm particles) is found
                      in saturation fields of 1.5 T compared with a particle
                      without this defect. Additionally, on the basis of Debye
                      scattering equation simulations, the influence of APBs on
                      X-ray powder diffraction patterns is shown. The Fourier
                      transform of the APB peak profile is developed to be used in
                      a whole powder pattern modelling approach to determine the
                      presence of APBs and quantify them by fits to powder
                      diffraction patterns. This is demonstrated on experimental
                      data, where it could be shown that the number of APBs is
                      related to the observed reduction in magnetization.},
