论文摘要
$ s = 2 $抗铁磁链的磁化高原与有限尺寸簇的数值对角线和一些尺寸缩放分析一起研究了与相互作用和单离子各向异性的磁化链。先前的水平光谱分析表明，两个不同的磁化平台出现在饱和磁化的一半。一种是由于$ d $机构的原因，另一个是由于haldane造成的。在本研究中，相图扩展到各向异性的更广泛区域。结果，我们发现了另一个半磁化平台阶段，其中翻译对称性自发损坏。
The magnetization plateau of the $S=2$ antiferromagnetic chain with interaction and single-ion anisotropies is investigated using the numerical diagonalization of finite-size clusters and some size scaling analyses. The previous level spectroscopy analysis indicated that two different magnetization plateau phases appear at half of the saturation magnetization. One is due to the large-$D$ mechanism and the other is due to the Haldane one. In the present study the phase diagram is extended to wider region of the anisotropies. As a result we find another half magnetization plateau phase, where the translational symmetry is spontaneously broken .
