高场磁化强度的测量进行了高达40 T的多级单重基态系统，Cs3Cr2X9（X=Cl，Br），具有层次较高的激发磁状态。在Cs3Cr2Cl9的磁化曲线中首次观察到了具有三个台阶的特征阶梯结构，并用交换耦合Cr3+二聚体模型（S =3）进行了分析.讨论了由于弱的二聚体间相互作用而引起的场致磁有序，并提出了一种由连续的能级交叉场周围的多个磁有序限制区组成的新型相图。
High field magnetization measurements were performed up to 40 T in the multilevel singlet ground state systems, Cs 3 Cr 2 X 9 (X=Cl, Br), having hierarchical higher excited magnetic states. Characteristic stair structure with three steps was observed, for the first time, in the magnetization curve of Cs 3 Cr 2 Cl 9 and analysed in terms of exchange-coupled Cr 3+ dimer model with the total spin S =3. Field-induced magnetic ordering due to weak interdimer interactions is discussed and a novel type of the phase diagram composed of multiple restricted regions of magnetic ordering around the successive level-crossing fields is suggested.
