Universal sublinear resistivity in vanadium kagome materials hosting charge density waves

Kagome metals are exciting platforms to explore electronic instabilities such as charge density waves. The authors study here magnetotransport properties of various kagome compounds, with a focus on the charge density wave metal ScV₆Sn₆ and explain characteristic features among them. For example, ScV₆Sn₆ and CsV₃Sb₅ both have charge density waves, and both exhibit sublinear resistivity above the charge ordering temperature and anomalous Hall-like behavior below this temperature. This contrasts with LuV₆Sn₆, which lacks charge ordering and lacks these intriguing transport hallmarks.
