The impact of hydrostatic pressure, nonstoichiometry, and doping on trimeron lattice excitations in magnetite during axis switching
T. Kołodziej, J. Piętosa, R. Puźniak +12
Trimeron lattice excitations in single crystalline magnetite, in the form of the axis switching (i.e. the reorganization of the lattice caused by external magnetic field) at te…
Trimeron-phonon coupling in magnetite
P. Piekarz, D. Legut, E. Baldini +11
Using density functional theory, we study the lattice dynamical properties of magnetite (FeO) in the high-temperature cubic and low-temperature monoclinic phases. The calcu…
Low-Temperature Magnetic Anomaly in Magnetite
Zdenek Svindrych, Zdenek Janu, Andrzej Kozlowski +1
We have studied experimentally the responses of high quality single crystals of stoichiometric synthetic magnetite to applied weak dc and ac magnetic fields in the range of 6 K to…
Zener double exchange from local valence fluctuations in magnetite
R. J. McQueeney, M. Yethiraj, S. Chang +4
Magnetite (FeO) is a mixed valent system where electronic conductivity occurs on the B-site (octahedral) iron sublattice of the spinel structure. Below K, a…
The Rectified Second Law of Thermodynamics
Dor Ben-Amotz, J. M. Honig
Equilibrium thermodynamics is combined with Jarzynski's irreversible work theorem to quantify the excess entropy produced by irreversible processes. The resulting rectified form of…
Investigation of the presence of charge order in magnetite by measurement of the spin wave spectrum
R. J. McQueeney, M. Yethiraj, W. Montfrooij +3
Inelastic neutron scattering results on magnetite (Fe3O4) show a large splitting in the acoustic spin wave branch, producing a 7 meV gap midway to the Brillouin zone boundary at q…
