The Valence State of Manganese in the Mn1/3NbS2 Magnet According to 55Mn-NMR Data

This paper presents the results of a study of the Mn1/3NbS2 magnet using the 55Mn nuclear magnetic resonance method in the absence of an external magnetic field. The results show that, in a magnetically ordered region, the manganese ions are in the same state with a valence of +3. At a temperature T = 4.2 K, the magnitude of the hyperfine field at the nucleus, hst = 448(6) kOe, and the mean magnetic moment of manganese, μ = 3.6 µB, are determined.
