Therefore the essential first step in building a full understanding of the role of CDW in establishing these unconventional phases is to unveil the symmetries and the microscopic nature of the charge-ordered phase. Here, we determine the exact structure of the 2×2×2 superlattice that develops below the charge-density wave ordering temperature (TCDW) in RbV₃Sb₅. We present a comprehensive set of ⁵¹V, ⁸⁷Rb, and ¹²¹Sb nuclear magnetic resonance (NMR) measurements and density functional theory simulations of NMR observables to provide a unique site-selective view into the local nature of the charge-ordered phase. The combination of these experimental results with simulations provides compelling evidence that the CDW structure prevailing below 103 K in RbV₃Sb₅ is the so-called inverse Star of David pattern, π-shifted along the c axis. These findings put severe constraints on the topology of these Kagome compounds and thus provide essential guidance for the development of an appropriate theoretical framework for predicting properties of exotic electronic orders arising within the CDW phase.</dc:description> <dc:identifier>https://archive.materialscloud.org/record/2024.22</dc:identifier> <dc:identifier>doi:10.24435/materialscloud:n0-va</dc:identifier> <dc:identifier>mcid:2024.22</dc:identifier> <dc:identifier>oai:materialscloud.org:2076</dc:identifier> <dc:language>en</dc:language> <dc:publisher>Materials Cloud</dc:publisher> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>Creative Commons Attribution Share Alike 4.0 International https://creativecommons.org/licenses/by-sa/4.0/legalcode</dc:rights> <dc:subject>Kagome Metal RbV3Sb5</dc:subject> <dc:subject>DFT</dc:subject> <dc:subject>Nuclear Magnetic Resonance</dc:subject> <dc:subject>Nuclear Quadrupole Resonance</dc:subject> <dc:title>Microscopic nature of the charge-density wave in the kagome superconductor RbV₃Sb₅</dc:title> <dc:type>Dataset</dc:type> </oai_dc:dc>
