Abstract

We report commensurate-to-incommensurate (C-IC) magnetic ordering in T_1/3NbS₂ (T=Cr and Mn), of which space group is P6₃22. We measured the anisotropic magnetization under magnetic fields applied perpendicular and parallel to the hexagonal c-axis. We observed a magnetization anomaly, only when the magnetic field was applied perpendicular to the hexagonal c-axis. The experimental results were in good agreement with the theoretical prediction based on a lattice chiral XY model, which describes the C-IC transition as chiral soliton formation. Therefore, we propose that the magnetic ordering in an incommensurate phase of T_1/3NbS₂ (T=Cr and Mn) can be chiral helimagnetic.
