We have investigated the surface termination and interlayer relaxations of Fe3O4(001) grown on MgO(001) by oxygen-plasma-assisted molecular beam epitaxy. Despite the fact that autocompensated surfaces can be constructed in principle by terminating with either a half layer of tetrahedral Fe, or a modified layer of octahedral Fe plus tetrahedral O, the combination of photoelectron diffraction and scanning tunneling microscopy suggest the former. The first four interlayer spacings are relaxed by-14%, -57%, -19%, and +29% of the respective bulk value. PACS numbers: 61.10Lx, 68.55.Bd.
