Abstract
Analytic expressions for the dispersion curves E(k) of RMnO3 (R=La, Pr, Nd, Sm, and other RE elements) have been obtained in the tight-binding approxi mation for the main types of magnetic ordering on the Mn sublattice. The fi rst calculation of E(k) taking into account the oxygen subsystem and mutual ordering of the manganese and RE sublattices is reported. The results obta ined permit a qualitative interpretation of some features observed in the b ehavior of the rare-earth manganites. (C) 1999 American Institute of Physic s. [S1063-7834(99)01412-4].
