(Minerals) a black magnetic mineral, found in igneous and metamorphic rocks and as a separate deposit. It is a source of iron. Composition: iron oxide. Formula: Fe3O4. Crystal structure: cubic magnetiticadj Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCol...
Mineral chemistry confirms the presence of two types of magnetites: magmatic (Mag‐I) and hydrothermal (Mag‐II). Mag‐I is octahedral, less commonly cubic, or irregular. It has a porous core with trellis‐type ilmenite exsolution lamellae. Mag‐II is non‐porous, devoid of ilmenite ...

For those reasons, magnetite is likely the most suitable natural magnetic mineral to accommodate the mechanism we consider. Modified ising model of the chirality-induced magnetization As is well established, the standard Ising model is a simplified model of a ferromagnet, and it accounts for the ...
magnetite [mag-ni-tahyt] Phonetic (Standard)IPA noun a very common black iron oxide mineral, Fe3O4, that is strongly attracted by magnets: an important iron ore. Word History and Origins Origin ofmagnetite1 1850–55;magnet+-ite1;compareGermanMagnetit...
The first known magnetic mineral, magnetite, has unusual properties, which have fascinated mankind for centuries; it undergoes the Verwey transition around 120 K with an abrupt change in structure and electrical conductivity. The mechanism of the Verwey transition, however, remains contentious. Here...

In this study, we investigated the redox transformation of mercuric Hg (Hg[II]) in the presence of the Fe(II)/Fe(III) mixed valence iron oxide mineral magnetite. Kinetic and spectroscopic experiments were performed to elucidate reaction rates and mechanisms. The experimental data demonstrated that...
Geochemical studies of magnetite from a wide range of mineral deposits have demonstrated that physico-chemical parameters such as temperature, pressure and oxygen fugacity (ƒO2) control its minor and trace element budget, particularly for Ti, V, Mn, Cr, Mg and Al1,2,3,4,5,6,7. ...
