Magnetostatic interactions in a natural magnetite-ulvospinel system [PDF]
, 2006 [ 1] Magnetostatic interactions have been investigated in anintergrown material consisting of similar to 200-nm magnetite blocksseparated by similar to 30-nm-wide ulvospinel lamellae. First-orderreversal curve (FORC) measurements provide a direct measure

Observations of viscous magnetization in multidomain magnetite [PDF]
, 2006 The viscous behavior of multidomain magnetite has been directly observed in both natural and synthetic samples using Bitter pattern imaging. A computer-controlled fully automated microscope fitted with a heating stage, field coils, and digital camera was

Necessity of electrically conductive pili for methanogenesis with magnetite stimulation [PDF]
PeerJ, 2018 Background Magnetite-mediated direct interspecies electron transfer (DIET) between Geobacter and Methanosarcina species is increasingly being invoked to explain magnetite stimulation of methane production in anaerobic soils and sediments.

Understanding viscous magnetization of multidomain magnetite [PDF]
, 2006 Viscous magnetization (VM) and viscous remanent magnetization (VRM) have been measured, as a function of temperature, between room temperature and the Curie temperature using a suite of well-characterized synthetic and natural multidomain (MD) magnetite ...

Magnetite and magnetotaxis in microorganisms
Bioelectromagnetics, 1988 AbstractMagnetotactic bacteria from freshwater and marine sediments orient and navigate along geomagnetic field lines. Their magnetotactic response is based on intracellular, single magnetic domains of ferrimagnetic magnetite, which impart a permanent magnetic dipole moment to the cell.

Magnetite in Sokli carbonatite massif and in Tulppio olivinite [PDF]
Bulletin of the Geological Society of Finland, 1981 Occurrence, ilmenite exsolutions and composition of magnetite in the carbonatite massif of Sokli and in the olivinite of Tulppio have been studied. In the carbonatite massif, magnetite of magmatic carbonatites is hypidio-idiomorphic, contains only very ...

Configurational anisotropy in single-domain and pseudosingle-domain grains of magnetite [PDF]
, 2006 In classical domain theory, single-domain (SD) grains change their magnetization by coherent rotation, where the energy barrier to domain reversal is provided by the magnetocrystalline anisotropy or by shape anisotropy for elongated grains.
