Abstract
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 ScV${}_{6}$Sn${}_{6}$ and explain characteristic features among them. For example, ScV${}_{6}$Sn${}_{6}$ and CsV${}_{3}$Sb${}_{5}$ 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 LuV${}_{6}$Sn${}_{6}$, which lacks charge ordering and lacks these intriguing transport hallmarks.
