  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.
