The mapping transformation technique is applied to obtain exact results for the spin-1/2 and spin- S ( S = 1/2, 1) Ising–Heisenberg antiferromagnetic chain in the presence of an external magnetic field. Within this scheme, a field-induced first-order metamagnetic phase transition resulting in multiplateau magnetization curves is investigated in detail. It is found that the scenario of the plateau formation depends fundamentally on the ratio between Ising and Heisenberg interaction parameters, as well as on the strength of the XXZ Heisenberg exchange anisotropy.
