Scanning tunneling microscopy of Fe- and O-sublattices on Fe3O4(100).

We present scanning tunneling microscopy of an octahedral (B) plane terminated (2×2)R45∘-reconstructed surface of a natural magnetite (100) crystal. Implementing a W-tip we achieve the same resolution on Fe rows as was reported in the past either with the use of antiferromagnetic tips or on magnetite (Fe3O4) films. We show images of Fe or O sublattices of Fe3O4 with atomic resolution.
