Quantitatively microscopic interpretations on magnetization-plateau phenomena in stacked triangular Ising antiferromagnets

A Monte Carlo method based on zero-temperature Glauber algorithm is employed to study field-induced magnetization-plateau behaviors in frustrated Ising antiferromagnets on stacked triangular lattices. The plateau heights and transitions are strongly dependent on ratios of interlayer to intralayer exchange constant. All the macroscopic phenomena have been quantitatively interpreted by means of microscopic spin orientations and evolutions. The same magnitude of exchange constants throughout the system opens new avenues along the stacking directions to spread intralayer frustration effects and to induce more active spin reversals. Accurate correspondence is also established, not only used to predict all the plateau transitions and heights but also to interpret the zero-field remanent magnetization as well as the magnetically hysteretic phenomena unambiguously.
