“…The resulting surface displayed the well-documented (H 2 Â H 2)R458 LEED pattern of the clean Fe 3 O 4 (001) surface, shown in Figure 5 (Mijiritskii et al, 2000;Stanka et al, 2000;Voogt et al, 1999). The surface cleanliness was confirmed by AES.…”

STM tips made from antiferromagnetic MnNi have been used to investigate the atomic structure of the (001) and (111) surfaces of Fe 3 O 4 . The clean (001) surface displays a (√2 × √2)R45° superlattice, which is attributed to charge-ordering on the surface, where Fe 2+ -Fe 2+ and Fe 3+ -Fe 3+ dimers can be discriminated. The oxygenterminated (111) surface is characterized by an hexagonal superlattice with a periodicity of 42 Å. Oxygen vacancies are observed in atomically resolved images of this superlattice. In the presence of an external magnetic field of 60 mT, a significant change in the atomic corrugation in the topmost oxygen layer around each of these defects is observed. The results on both (001) and (111) surfaces are discussed in terms of possible spin polarized effects.

“…The (001) surface of bulk magnetite has been the subject of many experimental studies aimed at determining its structure, using tools including low-energy electron diffraction [8,9], X-ray photoelectron diffraction [10], low-energy ion scattering [11,12], scanning tunneling microscopy [10,13,14,15] and spectroscopy [16]. The most common surface reconstruction, 2× 2R45°, has been alternatively interpreted as octahedral-iron √ √ terminated with a Jahn-Teller distortion [17] or as tetrahedral-iron terminated.…”

Micromagnetism in (001) magnetite by spin-polarized low-energy electron microscopy

et al. 2013

Spin-polarized low-energy electron microscopy was used to image a magnetite crystal with (001) surface orientation. Sets of spin-dependent images of magnetic domain patterns observed in this surface were used to map the direction of the magnetization vector with high spatial and angular resolution. We find that domains are magnetized along the surface <110> directions, and domain wall structures include 90° and 180° walls. A type of unusually curved domain walls are interpreted as Néel-capped surface terminations of 180° Bloch walls.

“…DOI Growing interest has been prompted in the investigation of Fe 3 O 4 (magnetite) as an important material in catalysis, corrosion, geochemistry, and magnetism. The preparation of Fe 3 O 4 plays a key role in this field of research and much literature has reported the growing of Fe 3 O 4 crystals on Pt [1][2][3][4], MgO [5][6][7][8], and Al 2 O 3 [9] substrates with different methods. Regarding the crystallographic properties, Fe 4 N nitride might not be a good candidate for preparing Fe 3 O 4 oxide, between which the lattice mismatch is up to 10%.…”

In SituObservation of the Formation ofFe3O4inFe

gamma(')-Fe4N was subjected to electron irradiation with the dose rate of 6.8 x 10(23)e m(-2) s(-1) in a 400 kV transmission electron microscope. The first in situ observation of the formation of Fe3O4 (O) on Fe4N (gamma(')) with the orientation relationship of [100](O) parallel [100](gamma(')) and <001>(O) parallel <001>(gamma(')) has been made inside the microscope with the basic column vacuum of (5-6) x 10(-5) Pa. A mechanism is proposed involving the electron-stimulated dissociation of Fe-N chemical bonds, desorption of nitrogen from the surface, adsorption of oxygen to the surface, and the oxidization of excessive metallic iron on the surface.
