The two-legged spin ladder NH4CuCl3 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 14.7T shows a clear kink at 4K. This is considered as the evidence for the field-induced magnetic order proposed by Kurniawan et al.
