The (100) face of magnetic Fe4N could have two different structures, which were studied here with scanning tunnelling microscopy and low-energy ion scattering as the main tools. The combination of these complementary methods led to a better interpretation of scanning tunnelling microscopic images, a precise determination of the structures, and provides better understanding of the driving force for the reconstruction. The atom positions were determined by comparing measured and simulated angular low-energy ion scattering scans. The merits of this program were briefly discussed.
