    • The good aspect of MnO is the existence of two magnetic interactions (Formula presented) and (Formula presented) which are of the same order of magnitude and, at the same time, of the different physical origin. Unfortunately, such a behavior is not a general feature for many antiferromagnetic Ni- and Cu-based perovkites (Formula presented) etc.), which also attracted considerable attention during recent years [e.g., R. L. Martin and F. Illas, Phys. Rev. Lett. 79, 1539 (1997)].

    • The interatomic magnetic interactions in such compounds are quite often restricted only by the nearest-neighbor (Formula presented) superexchange and, therefore, the one-to-one correspondence between the electronic structure and the interatomic magnetic interactions is violated: a variety of combinations of the parameters (Formula presented) can yield the same superexchange (Ref. 31). Thus, these are less interesting examples for the purposes of our work. Another interesting example where one might try to find a unambiguous connection between the electronic structure and the interatomic magnetic interactions is (Formula presented) [E. J. Samuelsen, M. T. Hutchings, and G. Shirane, Physica (Amsterdam) 48, 13 (1970)].

    • Note, however, that the band gap is larger than the 3.6-3.8 eV suggested by the photoconductivity measurements by R. N. Iskendorov, I. A. Drabkin, L. T. Emel’yanova, and Ya. M. Ksendzov, Fiz. Tverd. Tela (Leningrad) 10, 2573 (1968) [Sov. Phys. Solid State 10, 2031 (1969)]. We believe that the reason is in the incorrect position of the unoccupied free-electron-like parabolic band around the (Formula presented) point in the ASA.

    • It is known that for the transition metal oxides GGA corrects substantially the LSDA equilibrium volume and bulk moduli (even with a certain tendency to overcorrect), but only slightly retouches the band-gap problem [P. Dufek, P. Plaha, V. Sliwko, and K. Schwarz, Phys. Rev. B 49, 10 170 (1994).

    • For example, it is know that the particle-particle scattering underlying the Kanamori’s t-matrix approach [J. Kanamori, Prog. Theor. Phys. 30, 275 (1963)] can break the spin and orbital symmetry of unrenormalized Hartree-Fock interactions (Formula presented)[M. M. Steiner and J. W. Wilkins (unpublished)].
