    • The present value JH =0.6eV is consistent with the one obtained in Ref.19, where a different definition of JH was used. The derived estimate suggests a considerable screening of the atomic value (Ref.) of JH =0.9eV deduced from the Racah parameters B and C, see Ref.33.

    • As explained in the text, the effective parameter U is reduced from the intraorbital Coulomb interaction due to excitonic and polarization effects (Ref.) that accompany intersite optical transitions. The value of U deduced from the photoemission experiments, see, 10.1103/PhysRevB.46.3771, or used in recent electronic-structure calculations for LaMnO3 (Ref.) is ∼5eV.

    • The orbital angle θ may change somewhat near the magnetic transition at TN as the balance between the superexchange and the effective orbital interactions induced by the lattice distortions changes; this effect was ignored in the present analysis.

    • Note that the error bars quoted here reflect the statistical accuracy of the data and do not include systematic errors due to the assumptions underlying this determination. The same value of t=0.41eV was estimated also from the CT model, Ref., and provides a satisfactory description of the magnon excitation spectra in the ferromagnetic metallic manganites, see, 10.1103/PhysRevB.61.3494;
