Brillouin scattering studies in Fe3O4 across the Verwey transition
Brillouin scattering studies have been carried out on high quality single crystals of Fe3O4 with [100] and [110] faces in the temperature range of 300 to 30 K. The room temperature spectrum shows a surface Rayleigh wave (SRW) mode at 8 GHz and a longitudinal acoustic (LA) mode at 60 GHz. The SRW mode frequency shows a minimum at the Verwey transition temperature TV of 123 K. The softening of th...
متن کاملThe Verwey Transition in Magnetite
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.
متن کاملCharge-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...
متن کاملBrillouin scattering self-cancellation
The interaction between light and acoustic phonons is strongly modified in sub-wavelength confinement, and has led to the demonstration and control of Brillouin scattering in photonic structures such as nano-scale optical waveguides and cavities. Besides the small optical mode volume, two physical mechanisms come into play simultaneously: a volume effect caused by the strain-induced refractive ...
متن کاملInfrared and Raman Studies of the Verwey Transition in Magnetite. Typeset Using Revt E X 2
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
