Recently,giant intrinsic anomalous Hall effect(AHE)has been observed in the materials with kagome lattice.Here,we systematically investigate the influence of high pressure on the AHE in the ferromagnet LiMn6Sn6 with clean Mn kagome lattice.Our in situ high-pressure Raman spectroscopy indicates that the crystal structure of LiMn6Sn6 maintains a hexagonal phase under high pressures up to 8.51 GPa.The anomalous Hall conductivity(AHC)σAxy remains around 150 Ω-1·cm-1,dominated by the intrinsic mechanism.Combined with theoretical calculations,our results indicate that the stable AHE under pressure in LiMn6Sn6 originates from the robust electronic and magnetic structure.
