Properties of spin-3/2 transverse Ising model with anisotropic crystal field on a honeycomb lattice

The properties of spin-3/2 transverse Ising model with the anisotropic crys tal field interaction are studied by using the effective-field theory with correlations based on both the approximated Van der Waerden identity and th e differential operator technique. The longitudinal and transverse magnetiz ations and the internal energy and specific heat are obtained numerically f or the honeycomb lattice (z=3). We find a number of interesting phenomena i n these quantities, due to the fluctuation of anisotropic crystal field int eraction and the transverse field. (C) 2000 Elsevier Science B.V.
