Non-Reciprocal Zone Boundary Magnon Propagation in CuOSeO
Tobias Weber, Niclas Heinsdorf, Michal Stekiel +3
Inelastic neutron scattering in the chiral magnet CuOSeO reveals strong non-reciprocal effects on magnon propagation at the boundary of the nuclear Brillouin zone. The non-…
Direct evidence for anisotropic magnetic interaction in -RuCl from polarized inelastic neutron scattering
Markus Braden, Xiao Wang, Alexandre Bertin +2
Polarized neutron scattering experiments reveal the anisotropy of magnetic correlations in the candidate Kitaev material -RuCl. The anisotropy of the inelastic response at t…
Polarized inelastic neutron scattering of non-reciprocal spin waves in MnSi
Tobias Weber, Johannes Waizner, Paul Steffens +4
We report spin-polarized inelastic neutron scattering of the dynamical structure factor of the conical magnetic helix in the cubic chiral magnet MnSi. We find that the spectral wei…
Pseudospin-lattice coupling in the spin-orbit Mott insulator Sr2IrO4
J. Porras, J. Bertinshaw, H. Liu +15
Spin-orbit entangled magnetic dipoles, often referred to as pseudospins, provide a new avenue to explore novel magnetism inconceivable in the weak spin-orbit coupling limit, but th…
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…
Strong magnetoelastic coupling at the transition from harmonic to anharmonic order in NaFe(WO) with 3d configuration
S. Holbein, M. Ackermann, L. Chapon +9
The crystal structure of the double tungstate NaFe(WO) arises from that of the spin-driven multiferroic MnWO by inserting non-magnetic Na layers. NaFe(WO) exhib…

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…
Hourglass dispersion in overdoped single-layered manganites

The excitation spectrum in single-layered Nd(0.33)Sr(1.67)MnO4 and Pr(0.33)Ca(1.67)MnO4 resembles the hourglass-like excitation dispersion seen in various cuprates superconductors.…

Mickael Loire, Virginie Simonet, Sylvain Petit +9
The spin wave excitations emerging from the chiral helically modulated 120 magnetic order in a langasite BaNbFeSiO enantiopure crystal were investigate…
Evidence for charge orbital and spin stripe order in an overdoped manganite
H. Ulbrich, D. Senff, P. Steffens +5
We present diffraction data on a single-layered manganite La(0.42)Sr(1.58)MnO4 with hole doping (x>0.5). Overdoped La(0.42)Sr(1.58)MnO4 exhibits a complex ordering of charges, orbi…
