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 HfMn6Sn6,ZrMn6Sn6,GdMn6Sn6 and GdV6Sn6,by using the flux method with Sn as the flux.Among them,HfMn6Sn6 and ZrMn6Sn6 single crystals were grown for the first time.X-ray diffraction measurements reveal that all four samples crystallize in HfFe6Ge6-type hexagonal structure with space group P6/mmm.All samples show metallic behavior from temperature dependence of resistivity measurements,and the dom-inant carrier is hole,except for GdV6Sn6 which is electron dominated.All samples have magnetic order with different transition temperatures,HfMn6Sn6,ZrMn6Sn6 and GdV6Sn6 are antiferromagnetic with TN of 541 K,466 K and 4 K respectively,while GdMn6Sn6 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 mate-rials.The dataset of specific crystal structure parameters for HfMn6Sn6 are available in Science Data Bank,with the link https://doi.org/10.57760/sciencedb.j00113.00120.
