Abstract
Motivated in part by the success of the AV${}_{3}$Sb${}_{5}$ kagome superconductors, ongoing efforts to explore new kagome metals have led to the discovery of a range of materials exhibiting unique magnetic and electronic properties. In this study, the authors present novel vanadium-based kagome antimonides that incorporate the chemical flexibility of a rare-earth site, allowing for the intertwining of magnetic and charge degrees of freedom. These new compounds, namely EuV${}_{3}$Sb${}_{4}$ and YbV${}_{3}$Sb${}_{4}$, provide valuable insights into the relatively small LnM${}_{3}$X${}_{4}$ family and open up potential avenues for the realization of additional rare-earth, antimonide-based kagome metals.
