Crystal field and spin-wave excitations in the quasi-2D honeycomb zigzag antiferromagnet Na2Co2TeO6

Abstract: The microscopic origin of the zigzag magnetic ground state in a honeycomb lattice of the quasi-2D antiferromagnet Na2Co2TeO6 is debatable. The zigzag phase may occur due to (i) the J1-J2-J3 Heisenberg models for a wide range of exchange parameters, (ii) hierarchy of exchange interactions between nearest neighbours due to orbital ordering, or (iii) presence of strongly anisotropic interactions in the proximity of the Kitaev spin liquid. We propose inelastic neutron scattering measurements on Na2Co2TeO6 using the Merlin spectrometer to determine the origin of the zigzag ground state (out of the above three possibilities) as well as to explore the possible signature of quantum effects.
