Microwave absorption dynamics in Fe<sub>3</sub>O<sub>4</sub>nanopowders around Verwey transition

چکیده
Abstract In Fe 3 O 4 nanopowders were carried out microwave absorption measurements at X-band (8.8-9.8 GHz), in the 89-300 K temperature range, by means of ferromagnetic resonance (FMR), magnetically modulated spectroscopy (MAMMAS) and low-field (LFMA). The Verwey transition around T v ∼ 137 has been detected employed FMR parameters: resonant field ( H res ) linewidth ΔH pp ), as function. MAMMAS response shows features that can also be associated with transition. Finally, LFMA spectra are a magnetic state nanopowders, where lineal component positive slope hysteresis loop zero clearly observed, behavior suggests presence

The 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 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...
متن کاملLong range charge ordering in magnetite below the Verwey transition.
The crystal structure of Fe(3)O(4) below the 122 K Verwey transition has been refined using high-resolution x-ray and neutron powder diffraction data. The refinements give direct evidence for charge ordering (CO) over four independent octahedral Fe sites, two with a charge of +2.4 and the other two of +2.6. CO schemes consistent with our model do not meet the widely accepted Anderson condition ...
متن کاملMicrowave Absorption Peaks : Signatures of Spin Dynamics in Cuprates
We show that a common feature of temperature-dependent microwave absorption is the presence of absorption peaks. ac loss peaks can arise when the internal T -dependent magnetic relaxation time crosses the measurement frequency. These features are observed in the insulating (SrxCa14−xCu24O41, La5/3Sr1/3NiO4 and Y Ba2Cu3O6.0), pseudo-gap (T > Tc in underdoped Y Ba2Cu3O7−δ , Hg : 1223 and Hg : 120...
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...
