Abstract

Clean (100) surfaces of a synthetic single crystal of magnetite (Fe3O4) have been prepared in situ using current pulses in a scanning tunneling microscope without subsequent annealing. We have observed atomically resolved terraces with rows of Fe2+ and Fe3+ ions of the B-sublattice (octahedrally coordinated lattice sites). Along these rows a long-distance corrugation (~12 Å) has been observed at 300 K using in situ prepared Fe tunneling tips. This corrugation is interpreted as a Wigner localization associated with a Verwey transition above 300 K in the top surface layer.
