Ground-state phase diagrams mapped in the anisotropy-field plane.

Confirmation of previous predictions about the nematic phase.

Abstract

The magnetization process of the $S=1$ spin ladder system is investigated using the numerical exact diagonalization of finite-size clusters. The field-induced spin nematic liquid phase was predicted to appear by our previous work. Several ground-state phase diagrams in the plane of the single-ion anisotropy and the external magnetic field are obtained in the present study.
