FeGe is an antiferromagnetic kagome metal with a rich magnetic and electronic phase diagram. Recently it was found that post-growth annealing of FeGe can suppress or induce charge density wave order depending on the annealing temperature. Here, Klemm, Siddique et al show the critical role that annealing induced Ge-vacancies and stacking faults play in the formation of charge density wave order in FeGe.
