Abstract
By using the exact diagonalization method on finite-size clusters, the interplay of spin and orbital in the undoped insulating and doped charge-ordered states of perovskite manganites is examined. The spins lift the orbital degeneracy. As a result, the anisotropic antiferromagnetic states are obtained.
