Büchner, Bernd Balakrishnan, Geetha De Renzi, Roberto Allodi, Giuseppe 2025-01-28 The discovery of chiral helical magnetism (CHM) in Cr&lt;sub&gt;1/3&lt;/sub&gt;NbS&lt;sub&gt;2&lt;/sub&gt; and the stabilization of a chiral soliton lattice (CSL) has attracted considerable interest in view of their potential technological applications. However, there is an ongoing debate regarding whether the sister compound, Mn&lt;sub&gt;1/3&lt;/sub&gt;NbS&lt;sub&gt;2&lt;/sub&gt;, which shares the same crystal structure, exhibits similar nontrivial properties, which rely on the stabilization of the lack of inversion symmetry at the magnetic ion. In this study, we conduct a comprehensive investigation of the magnetically ordered states of both compounds, using &lt;sup&gt;53&lt;/sup&gt;Cr, &lt;sup&gt;55&lt;/sup&gt;Mn and &lt;sup&gt;93&lt;/sup&gt;Nb nuclear magnetic resonance. Our results, supported by density functional calculations, detect in a high quality single crystal of Cr&lt;sub&gt;1/3&lt;/sub&gt;NbS&lt;sub&gt;2&lt;/sub&gt; all the signatures of the monoaxial CHM in a magnetic field, identifying it as a textbook NMR case. The detailed understanding of this prototypic behavior provides a reference for Mn&lt;sub&gt;1/3&lt;/sub&gt;NbS&lt;sub&gt;2&lt;/sub&gt;. Despite the much larger density of specific defects in this second single crystal, we confirm the presence of a CHM phase in the Mn compound, characterized by a very large critical field for the forced ferromagnetic phase (~ 10 T for H || c). application/gzip text/markdown https://doi.org/10.24435/materialscloud:qa-5v oai:materialscloud.org:2547 mcid:2025.20 eng Materials Cloud https://doi.org/10.48550/arXiv.2410.01631 http://arxiv.org/abs/2410.01631 https://archive.materialscloud.org/communities/mcarchive https://doi.org/10.24435/materialscloud:et-9z info:eu-repo/semantics/openAccess Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/legalcode Chiral Helical Magnetism Nuclear Magnetic Resonance DFT Chiral Soliton Lattice Disorder-resilient transition of Helical to Conical ground states in M<sub>1/3</sub>NbS<sub>2</sub>, M=Cr,Mn info:eu-repo/semantics/other
