In this study, we have employed the classical transfer matrix technique to investigate the magnetization plateaus, phase diagrams and other thermodynamical properties of the one-dimensional antiferromagnetic spin-3/2 and spin-2 Ising chains with single-ion anisotropy in the presence of an external magnetic field at very low temperature. We have showed that single ion-anisotropy is one of the indispensable ingredients for an energy gap which leads to magnetic plateau mechanism in one-dimensional antiferromagnetic Ising spin chains. Other thermodynamical predictions seem to be provide this argument.
