The ground-state phase diagrams of the spin-3/2 Ising model

Abstract

The ground-state spin configurations are obtained for the spin-3/2 Ising model Hamiltonian with bilinear and biquadratic exchange interactions and a single-ion crystal field. The interactions are assumed to be only between nearest-neighbors. The calculated ground-state phase diagrams are presented on diatomic lattices, such as the square, honeycomb and sc lattices, and triangular lattice in the ( Δ/ z| J|, K/| J|) and ( H/ z| J|, K/| J|) planes.
