摘要： Kagome magnets were predicted to be a good platform to investigate correlated topology band structure, Chern quantum phase, and geometrical frustration due to their unique lattice geometry. Here we reported single crystal growth of 166-type kagome magnetic materials, including HfMn$_{6}$Sn$_{6}$, ZrMn$_{6}$Sn$_{6}$, GdMn$_{6}$Sn$_{6}$ and GdV$_{6}$Sn$_{6}$, by using the flux method with Sn as the flux. Among them, HfMn$_{6}$Sn$_{6}$ and ZrMn$_{6}$Sn$_{6}$ single crystals were grown for the first time. X-ray diffraction measurements reveal that all four samples crystallize in HfFe$_{6}$Ge$_{6}$-type hexagonal structure with space group P6/mmm. All samples show metallic behavior from temperature dependence of resistivity measurements, and the dominant carrier is hole, except for GdV$_{6}$Sn$_{6}$ which is electron dominated. All samples have magnetic order with different transition temperatures, HfMn$_{6}$Sn$_{6}$, ZrMn$_{6}$Sn$_{6}$ and GdV$_{6}$Sn$_{6}$ are antiferromagnetic with $T_{\rm N}$ of 541 K, 466 K and 4 K respectively, while GdMn$_{6}$Sn$_{6}$ is ferrimagnetic with the critical temperature of about 470 K. This study will enrich the research platform of magnetic kagome materials and help explore the novel quantum phenomena in these interesting materials. The dataset of specific crystal structure parameters for HfMn$_{6}$Sn$_{6}$ are available in Science Data Bank, with the link https://doi.org/10.57760/sciencedb.j00113.00120.
