Tilted and Twisted Magnetic Moments in the Kitaev Magnet -RuCl
Xiao Wang, Fengfeng Zhu, Markus Braden +8
The layered honeycomb magnet -RuCl has attracted intense scrutiny as a prime candidate for realizing the Kitaev quantum spin liquid, yet a consensus on its microscopic Hamil…
Magnetic excitations in the Kitaev material NaIrO studied by neutron scattering
Alexandre Bertin, Hengdi Zhao, Gang Cao +4
Inelastic neutron scattering experiments with a large set of comounted NaIrO crystals reveal the low-energy magnon dispersion in this candidate material for Kitaev physics.…
KOMPASS: the new cold neutron triple-axis-spectrometer specialized for polarization analysis
D. Gorkov, M. Müller, G. Waldherr +6
KOMPASS is a polarized triple-axis cold neutron spectrometer recently installed at the FRM II neutron source. The instrument is designed to operate exclusively with polarized neutr…
Crystal structure and absence of magnetic order in single crystalline RuO
Lara Kiefer, Felix Wirth, Alexandre Bertin +7
RuO was considered for a long time to be a paramagnetic metal with an ideal rutile-type structure down to low temperatures, but recent studies on single-crystals claimed eviden…
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…
