Abstract

The spin-one Ising system -βH = K i,j (SiSj+ηSi2Sj2) +k(hSk+ΛSk2) is considered. We have obtained high-temperature series for the free energy through eighth order for arbitrary η, h, and Λ by rewriting this Hamiltonian in a form which exploits its relation to the three-component Potts model (η=3). Explicit results are presented for the bcc lattice.
