The linked-cluster type of series expansions with a variational parameter are derived to the eighth order for the spin-S exchange-interaction model. These series expansions are analyzed to obtain phase transition temperatures (Formula presented), latent heats, and discontinuities of the order parameter at (Formula presented) for the face-centered-cubic lattice.
