Superconductivity in the kagome metal KVSb
arXiv:2012.09097 · doi:10.1103/PhysRevMaterials.5.034801
Abstract
Here we report the observation of bulk superconductivity in single crystals of the two-dimensional kagome metal KVSb. Magnetic susceptibility, resistivity, and heat capacity measurements reveal superconductivity below K, and density functional theory (DFT) calculations further characterize the normal state as a topological metal. Our results demonstrate that the recent observation of superconductivity within the related kagome metal CsVSb is likely a common feature across the AVSb (A: K, Rb, Cs) family of compounds and establish them as a rich arena for studying the interplay between bulk superconductivity, topological surface states, and likely electronic density wave order in an exfoliable kagome lattice.
