Quasimolecular electronic structure of the trimer iridate BaNbIrO
M. Magnaterra, A. Sandberg, H. Schilling +17
The insulating mixed-valent Ir compound BaNbIrO hosts two holes per IrO trimer unit. We address the electronic structure via resonant inelastic…
Spin-orbital-lattice entanglement in the ideal j=1/2 compound KIrCl
P. Warzanowski, M. Magnaterra, Ch. J. Sahle +9
Mott insulators with spin-orbit entangled j=1/2 moments host intriguing magnetic properties. The j=1/2 wave function requires cubic symmetry, while a noncubic crystal field mixes j…
Giant natural optical rotation from chiral electromagnons in a collinear antiferromagnet
D. Maluski, M. Langenbach, D. Szaller +8
In NiTeO with a chiral crystal structure, we report on a giant natural optical rotation of the lowest-energy magnon. This polarization rotation, as large as 140 deg/mm, cor…
Chiral excitations and the intermediate-field spin-liquid regime in the Kitaev magnet -RuCl
Anuja Sahasrabudhe, Mikhail A. Prosnikov, Thomas C. Koethe +6
In the Kitaev magnet -RuCl, the existence of a magnetic-field-induced quantum spin liquid phase and of anyonic excitations are discussed controversially. We address this elu…
RIXS observation of bond-directional nearest-neighbor excitations in the Kitaev material NaIrO
M. Magnaterra, K. Hopfer, Ch. J. Sahle +13
Spin-orbit coupling locks spin direction and spatial orientation and generates, in semi-classical magnets, a local spin easy-axis and associated ordering. Quantum spin-1/2's defy t…
RIXS interferometry and the role of disorder in the quantum magnet BaTiIrO
M. Magnaterra, M. Moretti Sala, G. Monaco +8
Motivated by several claims of spin-orbit driven spin-liquid physics in hexagonal BaTiIrO hosting Ir2O9 dimers, we report on resonant inelastic x-ray scattering…
