The Verwey Transition in Magnetite
نویسنده
چکیده
The historical development and theories explaining the Verwey transition in Magnetite are discussed. An overview of current experimental work is included. Also examined are multiple charge ordering theories and more sophisticated considerations of Jahn-Teller effects which attempt to explain this long-standing problem in strongly-correlated electron systems.

Charge-orbital ordering and Verwey transition in magnetite measured by resonant soft X-ray scattering.
We report experimental evidence for the charge-orbital ordering in magnetite below the Verwey transition temperature T(V). Measurements of O K-edge resonant x-ray scattering on magnetite reveal that the O 2p states in the vicinity of the Fermi level exhibit a charge-orbital ordering along the c axis with a spatial periodicity of the doubled lattice parameter of the undistorted cubic phase. Such...

We present infrared and Raman measurements of magnetite (Fe3O4). This material is known to undergo a metal-insulator and a structural transition (Verwey transition) at TV = 120 K. At temperatures below TV, we observe a
متن کاملRaman study of the Verwey transition in magnetite thin films
We have grown epitaxial thin films of magnetite on MgO and Al2O3 substrates with sharp and distinct signatures of the Verwey transition in resistivity and magnetization. We have used Raman scattering to separate the footprint of purely structural changes from the effect of additional charge and orbital order. Raman modes related to the structural phase transition occur first at temperatures abo...

Magnetite has a different electrical resistance behavior with temperatures below and above the Verwey temperature. Here, we report on Verwey transition in Fe3O4 by means of the frequency-doubled output from the Ti-sapphire laser in pump-probe experiments and from the insulator to metal transition observed by changing the temperature at the wavelength 370nm (~3.36 eV) both for pump and probe. We...
متن کاملCharge-orbital ordering and Verwey transition in magnetite.
Local density approximation + Hubbard U (LDA + U) band structure calculations reveal that magnetite (Fe3O4) forms an insulating charge-orbital-ordered state below the Verwey transition temperature. The calculated charge ordering is in good agreement with that inferred from recent experiments. We found an associated t(2g) orbital ordering on the octahedral Fe2+ sublattice. Such an orbital orderi...
