Magnetic Frustration Driven by Itinerancy in Spinel CoV2O4
J. H. Lee, J. Ma, S. E. Hahn +7
Localized spins and itinerant electrons rarely coexist in geometrically-frustrated spinel lattices. We show that the spinel CoV2O4 stands at the crossover from insulating to itiner…
Extended Magnetic Exchange Interactions in the High-Temperature Ferromagnet MnBi
T. J. Williams, A. E. Taylor, A. D. Christianson +6
The high-temperature ferromagnet MnBi continues to receive attention as a candidate to replace rare-earth-containing permanent magnets in applications above room temperature. This…
Influence of interstitial Mn on magnetism in room-temperature ferromagnet Mn(1+delta)Sb
A. E. Taylor, T. Berlijn, S. E. Hahn +10
We report elastic and inelastic neutron scattering measurements of the high-TC ferromagnet Mn(1+delta)Sb. Measurements were performed on a large, TC=434 K, single crystal with inte…
Strong competition between orbital-ordering and itinerancy in a frustrated spinel vanadate
J. Ma, J. H. Lee, S. E. Hahn +11
The crossover from localized- to itinerant-electron behavior is associated with many intriguing phenomena in condensed-matter physics. In this paper, we investigate the crossover f…
Inelastic neutron scattering studies of YFeO
S. E. Hahn, A. A. Podlesnyak, R. S. Fishman +5
Spin waves in the the rare earth orthorferrite YFeO have been studied by inelastic neutron scattering and analyzed with a full four-sublattice model including contributions fro…
Magnetism dependent phonon anomaly in LaFeAsO observed via inelastic x-ray scattering
S. E. Hahn, G. S. Tucker, J. -Q. Yan +7
The phonon dispersion was measured at room temperature along (0,0,L) in the tetragonal phase of LaFeAsO using inelastic x-ray scattering. Spin-polarized first-principles calculatio…
