Abstract
Abstract We have carried out muon spin relaxation and rotation measurements on the newly discovered kagome metal KV 3 Sb 5 , and find a local field dominated by weak magnetic disorder which we associate with the nuclear moments present, and a modest temperature dependence which tracks the bulk magnetic susceptibility. We find no evidence for the existence of V 4+ local moments, suggesting that the physics underlying the recently reported giant unconventional anomalous Hall effect in this material warrants further studies.
