摘要: The kagome lattice hosts unique electronic structure with Dirac fermions, van Hove singularities, and flat bands, which has been subjected to intensive study in recent years. We report herein the observation of significantly enhanced magnetism including a very large coercive magnetic field up to 4.7 T, optimized magnetic energy product with the maximum value of 45 kJ/m$^{3}$, and an increased magnetic ordering temperature reaching 113 K in Mn-substituted kagome metal TbV$_{6}$Sn$_{6}$, namely, TbV$_{5}$MnSn$_{6}$. Besides, both topological Hall-like and anomalous Hall effects are detected, with the latter being primarily dominated by intrinsic Berry curvature as indicated by our data analysis and theoretical calculations. Our work establishes an effective route for engineering the physical properties of kagome magnets. The results also provide valuable insights into the interplay between magnetism and topological states of the kagome lattice.
