Crystal growth and investigation of metallic kagome magnet GdMn6Ge6 — •Katharina M. Zoch, Kristin Kliemt, and Cornelius Krellner — Physikalisches Institut, Goethe-Universität Frankfurt, 60438 Frankfurt am Main, Germany

Metallic kagome systems show topologically nontrivial magnetic and electronic structures with the AT6X6-compounds counting as one of the prototypes of this material class [1]. The unique magnetism and interesting band structure makes them an ideal family to tune exotic magnetic and topological states using external parameters. So far, most work is based on polycrystalline samples, especially for the AMn6Ge6 (A = lanthanide) compounds. The typical self-flux crystal growth is challenging and has only been successfully performed for compounds with AMn6Ge6 (A = Tb-Lu) [2]. Here, we present the growth of GdMn6Ge6 crystals using a self-flux method as well as their chemical and physical characterization.
