Recently, the materials Cr1/3NbS2 have piqued the interest of researchers as rare examples of 2D materials with helical magnetic ordering, thought to occur due to competition between exchange and DMI. When a magnetic field is applied perpendicular to the c-axis, the helical ground state transforms into the chiral soliton lattice (CSL). A chiral conical phase (CCP) emerges when the magnetic field is applied along the c-axis. Both phases are well established in Cr3/NbS2. However, the other member of the family, Mn1/3NbS2 has a similar crystal structure but complex magnetic behavior. Cr single-crystal NMR measurements demonstrate the first-order nature of the helical-to-paramagnetic phase transition and determine the exact boundaries of the conical phase. Similarities with Mn single crystal NMR results are discussed.
