Abstract

The ferromagnetic exchange-interaction model on the simple-cubic lattice is studied by considering the effective Hamiltonian of a cluster of eight spins which form a cubic unit cell. Through the use of the Bogoliubov inequality and a group-theoretical method, thermodynamic properties of the model are examined. Critical parameters are then determined for general spins.
