Abstract
The transverse Ising model with four spin interactions is studied with in the finite cluster approximation (FCA), on a honeycomb and a square lattice. We have investigated the influence of the four spin interact ions on the phase diagrams of the system and on both longitudinal and transversal magnetizations. We have also shown that the tricritical ph enomenon exists only for low values of the transverse field. (C) 1998 Elsevier Science B.V. All rights reserved.
