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…

Multiple Spin-Orbit Excitons and the Electronic Structure of -RuCl
P. Warzanowski, N. Borgwardt, K. Hopfer +7
The honeycomb compound -RuCl is widely discussed as a proximate Kitaev spin-liquid material. This scenario builds on spin-orbit entangled moments arising for a $t…
