摘要：
A theoretical study of the interrelation of the crystal structure, charge, orbital, and magnetic subsystems in R(1-x)A(x)MnO(3) charge-ordered manganites has been carried out (where R3+ is the rare earth ion, A(2+) is the alkaline earth metal ion, x = 0.5, 2/3). The model of orbital-dependent exchange interactions and single-ion anisotropy is used. The presence of quasi-low-dimensional magnetic structures is exhibited. The spin waves spectra and antiferromagnetic resonance spectra are calculated.
