a Face centred cubic spinel structure of magnetite b

In the equilibrium bulk structure the distance between the octahedrally coordinated iron atoms Fe oct and the nearest neighboring oxygen atoms O in bulk magnetite is Å

Charge ordered structure of magnetite below the Verwey

The crystal structure of highly stoichiometric magnetite Fe 3 O 4 below the Verwey transition has been refined from high resolution neutron and synchrotron x ray powder diffraction data The refined model has a monoclinic P 2 / c symmetry cell with orthorhombic Pmca pseudosymmetry constraints on the atomic positions and contains four independent

Charge order and three site distortions in the Verwey

The mineral magnetite Fe3O4 undergoes a complex structural distortion and becomes electrically insulating at temperatures less than 125 kelvin Verwey proposed in 1939 that this transition is driven by a charge ordering of Fe2 and Fe3 ions but the ground state of the low temperature phase has remained contentious because twinning of crystal domains

A density functional theory investigation of the electronic structure

We note that we used a different crystal structure the PBE U structure in figure 5 a while we used the optimal PBE structure in figure 2 b In spite of some similarities in the description of electronic structures of bulk magnetite there is a noticeable difference in the band gap energies and the nature of the Fe 3 d orbitals near the

Impact of Nanocellulose Loading on the Crystal Structure

The XRD patterns of the Fe 3 O 4 NC composites were previously shown and the results revile change in nanocellulose structure from cellulose II to cellulose I after Fe 3 O 4 functionalization The decrease in peaks intensity of the magnetite phase is also detected due to overall increase in the NC content within Fe 3 O 4 NC1 to Fe 3 O 4

The structure of magnetite Semantic Scholar

The distribution of cations between tetrahedral A sites and octahedral B sites in ferrite spinels has been studied using K edge x ray absorption spectroscopy using excellent agreement with measured values pointing to the reliability of the measured occupancy factors

Anaerobic Digestion of Chicken Manure in the Presence of Magnetite

The influence of magnetite nanoparticles granular activated carbon GAC and biochar as well as their combinations on the anaerobic digestion of chicken manure and the structure of microbial communities was studied The addition of magnetite GAC and biochar increased the rate of methane production and the total methane yield It has been observed

Effect of crystal defects and internal stress on the

structure and magnetic properties of magnetite Ozden Ozdemir and David J Dunlop Department of Physics Erindale College University of Toronto Mississauga Ontario Canada Abstract Domain structures in magnetite are very sensitive to crystal imperfections which play a major role in hysteresis and remanence by hindering the motion of domain

The Shape Anisotropy in the Magnetic Field Assisted Self Assembly Chain

A series of Fe3O4 particle chains with an average particle diameter of 150 nm and different lengths were synthesized by using the self assembly method at reduced temperature in different synthesizing magnetic fields The influence of synthesizing magnetic field on the properties of the magnetite particle chains was studied by structural analyses magnetometry
