两条腿的自旋梯NH{sub 4}CuCl{sub 3}具有无带隙的基态，并且在磁化曲线中显示两个台阶平台。在14.7 T附近测得的Cu-NMR共振位移的温度依赖性在4 K处显示出明显的扭结。这被认为是Kurniawan等人提出的场致磁序的证据。
The two-legged spin ladder NH{sub 4}CuCl{sub 3} has a gapless ground state and shows two-step plateaus in the magnetization curve. The temperature dependence of the Cu-NMR resonance shift measured around 14.7 T shows a clear kink at 4 K. This is considered as the evidence for the field-induced magnetic order proposed by Kurniawan et al.
