Abstract

The ground-state (GS) phase diagrams of spin-3/2 Ising model for ferromagnetic/antiferromagnetic (FM/AFM) interactions on a two-layer lattice are studied under a constant magnetic field by varying the crystal field values for general coordination number q in detail. Thus, it is found that the system exhibits twenty-nine topologically different GS configurations according to their GS phase diagrams obtained in the (J(2)/J(1), J(3)/qJ(1)) planes. As the crystal field becomes more and more negative, the remaining phase configurations in the phase diagrams include only spin +/- 1/2 values as expected.
