The relevant model Hamiltonian contains exchange and quadrupolar interaction terms, associated with the parameters J1 and J2, respectively. We have found that the model under study has a very rich ground state diagram in the (J1,J2)-plane, with one ordered (ferromagnetic) state and three regions of different frustrated states. © 1995. |
