AbstractThe isotropic limit of spin systems with orbital degeneracy has global SU(4) symmetry. On many 2D lattices, the ground state does not possess long-range order, which may explain the observed spin liquid properties of LiNiO2. In the SU(4) Néel-ordered state, spin-spin correlations can be antiferromagnetic between two neighboring sites with parallel magnetic moments.
