Abstract: The method of the effective-field theory with self-spin correlations and the differential operator technique is used to study the magnetic properties of the spin-3/2 Ising model with biaxial crystal-field on the honeycomb lattice. The effects of a biaxial crystal-field described by two uniaxial anisotropy parameters Dx and Dy on the phase transition and specific heat and susceptibility are studied analytically and numerically. Some characteristic phenomena are found in the system such as tricritical behavior depending sensitively on the strength of the biaxial crystal-field.
