Incommensurate spin density waves in iron aluminides.
Neutron diffraction in Fe(Al) reveals incommensurate spin density waves (SDWs) in alloys known to be spin glasses. The wave vectors for crystals of Fe(34Al), Fe(40Al), and Fe(43Al) show n varying from 11 to 6 for q-->=2pi(h+/-1/n,k+/-1/n,l+/-1/n)/a(0), where (h,k,l) and a(0) characterize the parent bcc lattice of the CsCl structure. The magnetic reflections are present far above the spin-glass ...
متن کاملElectron correlation and spin density wave order in iron pnictides.
We study the correlation effects on the electronic structure, orbital and spin density wave (SDW) order in Fe pnictides. Using the multiorbital Hubbard model and Gutzwiller projection, we show that correlation effects are essential to stabilize the metallic SDW phase for the intermediate correlation strengths appropriate for pnictides. We find that the ordered moments depend sensitively on Hund...
متن کاملSpin excitations in the excitonic spin-density-wave state of the iron pnictides
Motivated by the iron pnictides, we examine the spin excitations in an itinerant antiferromagnet where a spin-density wave SDW originates from an excitonic instability of nested electronlike and holelike Fermi pockets. Using the random-phase approximation, we derive the Dyson equation for the transverse susceptibility in the excitonic SDW state. The Dyson equation is solved for two different tw...

متن کاملMulticenter Validation of Spin-Density Projection-Assisted R2-MRI for the Noninvasive Measurement of Liver Iron Concentration
PURPOSE Magnetic resonance imaging (MRI)-based techniques for assessing liver iron concentration (LIC) have been limited by single scanner calibration against biopsy. Here, the calibration of spin-density projection-assisted (SDPA) R2-MRI (FerriScan®) in iron-overloaded β-thalassemia patients treated with the iron chelator, deferasirox, for 12 months is validated. METHODS SDPA R2-MRI measurem...
