Spin Hamiltonian of the spin-1/2 chain system beta-TeVO4
Spin-nematic correlations are predicted as a generic feature of the frustrated ferromagnetic zigzag S=1/2 J1-J2 chain model. The ultimate experimental evidences however are rather limited, i.e. for LiCuVO4, so their number should be extended. The proposed INS experiment aims to measure spin excitations in a new frustrated ferromagnetic zigzag S=1/2 J1-J2 chain compound beta-TeVO4. The data will be used for determination of the effective spin Hamiltonian.
