Magnetocrystalline anisotropy of magnetite

Journal of Physics: Condensed Matter, 2012
The spin reorientation temperature T(SR) of stoichiometric Fe(3)O(4), as well as of magnetite with a small number of vacancies and magnetite containing a low concentration of Ti, Zn, Al and Ga was measured on single-crystal samples using the ac susceptibility. In the same experiment the temperature T(V) of the Verwey transition was also found.

Electronic processes in magnetite (or, "Enigmas of magnetite")

Physics-Uspekhi, 1993
The properties of magnetite in the region of the low-temperature transformation Tt = 100 – 120 K are in many respects still unclear and even enigmatic, in spite of the enormous number of studies that have been undertaken over the years. In this review article a new model for the low-temperature transformation in magnetite is presented, based on an ...

Magnetite Nucleation and Growth

2016
Magnetite is a ubiquitous iron oxide mineral found in Earth and planetary settings where its magnetic properties are, e.g., used to reconstruct past climates. Magnetite can also be biomineralized, i.e., formed by organisms such as magnetotactic bacteria or some mollusks (chitons), where the mineral is used either for its magnetic properties as compass ...

Synthesis and characterization of magnetite nanoparticles from mineral magnetite

Journal of Magnetism and Magnetic Materials, 2013
Abstract We have synthesized magnetite nanoparticles with sizes that range from 20 to 30 nm from mineral magnetite roughly 45 μm in size. The procedure consists in the dissolution of the mineral in an acidic medium and subsequent precipitation in a basic medium in the presence of oleic acid.

Low-temperature treatments of magnetite and magnetite-bearing rocks

Journal of Geophysical Research, 1970
Low-temperature treatments and alternating-field demagnetization of magnetite samples are compared. Both theory and experiments show that these treatments affect different parts of the coercive force spectrum of magnetite. Some secondary magnetization can survive low-temperature ‘cleaning.’ The combination of low-temperature treatment with af ...
