Abstract

The quantum spin magnet NH₄CuCl₃ is an antiferromagnetic dimer system, which has a magnetic ground state, and shows two-stepped magnetization plateaus. The origin of the plateaus and the detailed spin structure is not well understood. We have investigated the NMR spectra of deuterated ND₄CuCl₃ in the field region of the first plateau. Resonance peaks of the Cl-NMR spectra are classified into two groups with different temperature dependences. This indicates the existence of magnetically inequivalent dimers which are localized in space. Rotation profiles of the ²D-NMR spectra show many small peaks, indicating that the NH₄ molecules are oriented in a finite number of directions.
