Annealing tuned charge-density-wave order in the Kagome metal FeGe
ORAL
Abstract
Kagome metals have garnered much recent attention owing to their highly unconventional properties that can lead to the emergence of intriguing quantum phases [1]. For example, the kagome materials AV3Sb5 (A = K, Rb, Cs) [2] host an intriguing interplay between unconventional superconductivity and charge-density-waves (CDW). Recently a CDW was discovered in the antiferromagnetically ordered kagome metal FeGe [3-5]. Recent works demonstrate that the CDW in FeGe can be influenced strongly by post-growth annealing treatments [6]. Here, we investigate a series of post annealed FeGe crystals using the high-resolution dilatometry, calorimetry and magnetization measurements, as well as by single crystal x-ray diffraction.
