Abstract This investigation is devoted to a theoretical study of the role of orbital ordering in the magnetic frustration of the pseudoperovskite manganite La1/3Ca2/3MnO3. In the current study, the effect of orbital ordering on magnetic competition is described within the framework of orbitally-dependent superexchange interaction. The ranges of the mixing angles in the orbital structure of frustrated magnetic structures are determined. An orbitally-dependent single-ion anisotropy that takes octahedra tilting into account is proposed as the cause for strongly non-collinear magnetic ordering. The magnetic field dependences of complicated magnetic structures are discussed.
