Abstract:

A study is reported on the relation between orbital ordering and the magnetic structure of an LaMnO3 crystal. The dependence of the exchange parameters on the orbital-structure angle Phi has been determined. Inclusion into the spin Hamiltonian of isotropic exchange interaction and single-ion anisotropy, which depends on the angle Phi and rotational distortions, results in a four-sublattice structure (A(X), F-Y, G(Z)), with the sublattice magnetic moments oriented close to the long axis of the orthorhombic cell in the basal plane of the crystal (A(X) >> G(Z), F-Y). The effect of the rare-earth-ion size in RMnO3 manganites on the orbital and magnetic structures is considered. (C) 2000 MAIK ``Nauka /Interperiodica{''}.
