Abstract

The kagome lattice system has been identified as a fertile ground for the emergence of a number of new quantum states,including superconductivity,quantum spin liquids,and topological electronic states.This has attracted significant interest within the field of condensed matter physics.Here,we present the observation of an anomalous Hall effect in an iron-based kagome antiferromagnet LuFe6Sn6,which implies a non-zero Berry curvature in this compound.By means of extensive magnetic measurements,a high Neel temperature,TN=552 K,and a spin reorientation behavior were identified and a simple temperature-field phase diagram was constructed.Furthermore,this compound was found to exhibit a large Sommerfeld coefficient of γ=87 mJ·mol-1·K-2,suggesting the presence of a strong electronic correlation effect.Our research indicates that LuFe6Sn6 is an intriguing compound that may exhibit magnetism,strong correlation,and topological states.
