Abstract
The R compounds are characterized by an instability of the Mn moment in a highly frustrated crystallographic structure. Although quite general, this problem has not yet been treated. A model derived from the Hubbard Hamiltonian is proposed. It accounts for the new physics observed: complex ordered phases where magnetic and nonmagnetic sites coexist and unusual dependence on external parameters.
