论文摘要
$ s = 1/2 $铁磁 - 抗磁磁键 - 抗链接链自旋链具有各向异性在磁场中的铁磁交换相互作用上的各向异性，并使用数值对角度和密度矩阵renortrix Renormatorization组分析进行了研究。已经发现，外部磁场诱导了列型旋转主导的tomonaga-luttinger液相，以实现足够大的各向异性。提出了相对于各向异性和磁化的相图。
The $S=1/2$ ferromagnetic-antiferromagnetic bond-alternating spin chain with the anisotropy on the ferromagnetic exchange interaction in magnetic field is investigated using the numerical diagonalization and the density matrix renormalization group analyses. It is found that the nematic-spin-dominant Tomonaga-Luttinger liquid phase is induced by the external magnetic field for sufficiently large anisotropy. The phase diagram with respect to the anisotropy and the magnetization is presented.
