Investigation of spin excitations in candidate Kitaev magnet Na2Co2TeO6
Na2Co2TeO6 has recently been proposed to be a Kitaev-like magnet and was experimentally found to exhibit some resemblances with previous Kitaev materials. We propose to perform an inelastic neutron scattering experiment on Na2Co2TeO6 single crystals. The spin excitation spectrum in the magnetically ordered states will be carefully measured. By fitting the excitation spectrum, we will determine the leading interactions in this compound, which will allow us to assess how close it is to the Kitaev model. To further explore possible unconventional spin excitations, we will also make measurement well above the magnetic ordering temperature.
