28. Note that U and (Formula presented) are defined with respect to the (Formula presented) state, in contrast to other conventions (Refs. 17 and 19).
29. Different symmetry-broken states are degenerate at (Formula presented) as in the (Formula presented) model (Ref. 12), revealing a high frustration of magnetic interactions which might lead to a spin liquid with strong orbital correlations. Such quantum behavior is suppressed for the parameters of (Formula presented) with sizable (Formula presented) and because of the large (Formula presented) spins.

31. The MF values typically overestimate transition temperatures by a factor close to 1.6; it reduces the used MF value of (Formula presented) to the observed (Formula presented)
