| Popis: | The energy band spectra E(k) and densities of states are calculated for two-sublattice antiferromagnetic A, C and G phases of electron-doped manganites accounting for the Jahn–Teller splitting of the degenerate eg-level consistent with the orbital ordering. The canting of spin sublattices lifts the degeneracy of energy bands. The corresponding magnetic phase diagrams exhibit G, C and A magnetic phases compatible with the relevant experiments. |
