Spin-orbiton and quantum criticality in FeSc2S4 [PDF]

open access: yes, 2015
In FeSc2S4 spin-orbital exchange competes with strong spin-orbit coupling, suppressing long-range spin and orbital order and, hence, this material represents one of the rare examples of a spin-orbital liquid ground state.
