Spin dynamics and exchange interactions in Na2RuO3: an inelastic neutron scattering study

Abstract: Special attention has been devoted to the honeycomb iridates (Na, Li)2IrO3, in which SOC, intrinsic geometric frustration, and other competing interactions favor a highly anisotropic Kitaev exchange interactions that stabilizes exotic ground states such as quantum spin liquids (QSL). While such novel ground state has not yet been realized, largely due to competing isotropic interactions (Heisenberg) that stabilize magnetic order and/or lattice distortions that relieve geometrical frustration, searches for Kitaev and related QSLs are still ongoing. Here we propose to investigate the unexplored energy scales and relevant magnetic interactions present in the recently grown honeycomb ruthenate Na2RuO3 by means of powder inelastic neutron scattering. Along with our concurrent proposal submitted to WISH, we aim to establish the Hamiltonian describing the magnetic interactions in Na2RuO3.
