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%…
Magnon dispersion in Ca2RuO4: impact of spin-orbit coupling and oxygen moments
S. Kunkemöller, E. Komleva, S. V. Streltsov +6
The magnon dispersion of CaRuO has been studied by polarized and unpolarized neutron scattering experiments on crystals containing 0, 1 and 10 % of Ti. The entire dispersio…
Highly anisotropic magnon dispersion in Ca2RuO4: evidence for strong spin orbit coupling
S. Kunkemöller, D. Khomskii, P. Steffens +3
The magnon disp ersion in Ca2RuO4 has been determined by inelastic neutron scattering on single crytals containing 1% of Ti. The dispersion is well described by a conventional Heis…
