Competing exchange interactions on the verge of a metal-insulator transition in the two-dimensional spiral magnet SrFeO
J. -H. Kim, Anil Jain, M. Reehuis +12
We report a neutron scattering study of the magnetic order and dynamics of the bilayer perovskite SrFeO, which exhibits a temperature-driven metal-insulator transition…
Excitonic quasiparticles in a spin-orbit Mott insulator
Jungho Kim, M. Daghofer, A. H. Said +4
In condensed matter systems, out of a large number of interacting degrees of freedom emerge weakly coupled particles, in terms of which most physical properties are described. For…
Low energy magnetic excitations in the spin-orbital Mott insulator SrIrO
S. Bahr, A. Alfonsov, G. Jackeli +6
We report a high-field electron spin resonance study in the sub-THz frequency domain of a single crystal of SrIrO that has been recently proposed as a prototypical spin-orb…
Electronic excitations in the edge-shared relativistic Mott insulator: NaIrO
Beom Hyun Kim, G. Khaliullin, B. I. Min
We have investigated the excitation spectra of = Mott insulator NaIrO. Taking into account a relativistic multiplet structure of Ir ions, we have calc…
Theory of Raman and Resonant Inelastic X-ray Scattering from Collective Orbital Excitations in YTiO
L. J. P. Ament, G. Khaliullin
We present two different theories for Raman scattering and Resonant Inelastic X-ray Scattering (RIXS) in the low temperature ferromagnetic phase of YTiO and compare this to the…
Impurity-induced spin polarization and NMR line broadening in underdoped cuprates
R. Kilian, S. Krivenko, G. Khaliullin +1
We present a theory of magnetic (S=1) Ni and nonmagnetic Zn impurities in underdoped cuprates. Both types of impurities are shown to induce S=1/2 moments on Cu sites in the proximi…
