Single crystal growth and characterization of 166-type magnetic Kagome metals

Materials are an indispensable basis for experimental research. Subsequently, they are used to verifying the novel physical properties predicted by theories and exploring novel quantum effects, and are also the fundamental premise for the practical application. Compared with polycrystalline, single crystal has the following advantages: First, it can directly reflect the intrinsic properties of material because of no influence of grain boundaries, crystal domains, etc.; Secondly, due to the strong relationship between the axis of crystal and physical properties, high-quality single crystal samples must be prepared for studying the anisotropy of properties. Therefore, it is very important to synthesize high quality single crystal samples. In this paper, a type of 166 Kagome metal single crystals was successfully synthesized, and the crystal structure of HfMn6Sn6 single crystal was analyzed by single crystal X-ray diffraction measurement. The sample and crystal data, data collection and structure refinement, atomic coordinates and equivalent isotropic atomic displacement parameters, bond lengths and bond angles are obtained. Meanwhile, the crystal structure database is enriched.
