Lattice Dynamics of LiFeAs studied by Inelastic Neutron Scattering and Density Functional Theory calculations
Akshay Tewari, Navid Qureshi, Rolf Heid +6
We investigated the lattice dynamics of the unconventional superconductor LiFeAs using inelastic neutron scattering experiments and density-functional theory (DFT) calculations. By…
Rearrangement of orbitals in KAgF3 due to Kugel-Khomskii mechanism: a Neutron diffraction and Density Functional Theory study
Kacper Koteras, Sebastian Biesenkamp, Paolo Barone +6
The crystal structure of KAgF3 was studied by powder neutron diffraction. KAgF3 exhibits at all temperatures an orthorhombic symmetry in space group Pnma that allows for several di…
Structural dimerization in the commensurate magnetic phases of NaFe(WO) and MnWO
S. Biesenkamp, N. Qureshi, Y. Sidis +3
The structural distortion and magnetoelastic coupling induced through commensurate magnetism has been investigated by neutron diffraction in structurally related MnWO and NaFe(…
Interplay of electronic and spin degrees in ferromagnetic SrRuO: anomalous softening of magnon gap and stiffness
Kevin Jenni, Stefan Kunkemöller, Daniel Brüning +7
The magnon dispersion of ferromagnetic SrRuO was studied by inelastic neutron scattering experiments on single crystals as function of temperature. Even at low temperature the…
Spin-orbit entangled j=1/2 moments in BaCeIrO -- a frustrated fcc quantum magnet
A. Revelli, C. C. Loo, D. Kiese +16
We establish the double perovskite BaCeIrO as a nearly ideal model system for j=1/2 moments, with resonant inelastic x-ray scattering indicating a deviation of less than 1%…
Spin fluctuations in Sr2RuO4 from polarized neutron scattering: implications for superconductivity
P. Steffens, Y. Sidis, J. Kulda +4
Triplet pairing in Sr2RuO4 was initially suggested based on the hypothesis of strong ferromagnetic spin fluctuations. Using polarized inelastic neutron scattering, we accurately de…
