      abstract     = {The occurrence of antiferromagnetic coupling at antiphase
                      domain boundaries (APBs) of ferromagnetic materials holds
                      potential applications for room-temperature spintronic
                      devices. Here, we report formation mechanism and
                      atomic-scale structure properties of APBs in α-Li0.5Fe2.5O4
                      thin films on MgAl2O4 (001) substrates investigated by means
                      of aberration-corrected scanning transmission electron
                      microscopy. The APBs in the α-Li0.5Fe2.5O4 films are either
                      conservative or non-conservative. Across the APBs the oxygen
                      sublattice in α-Li0.5Fe2.5O4 is maintained, while the
                      stacking sequence of the cation sublattice is interrupted.
                      The propagation of APBs is found to occur in a complex way
                      within the ferromagnetic films, including the dissociation
                      of APBs and the formation of kinks. Importantly, the density
                      of APBs can be tuned by controlling the thickness of the
                      α-Li0.5Fe2.5O4 films since the APBs bound interfacial
                      dislocations contributing to film-substrate strain
                      relaxation. Our results evidence that the nano-scale APBs in
                      the α-Li0.5Fe2.5O4 films are controllable and stable, which
                      could be promising candidates for applications in
                      nano-spintronic devices.},
