Engineering Magnetic and Topological Electronic Properties in a Kagome Magnet Tb(Mn,Cr)₆Sn₆

Kagome magnets provide a rich platform for the study of interplay among electronic topology, magnetism, and lattice geometry. Fine composition manipulation in these systems can dramatically alter their spin configurations and topological electronic responses. In this work, we report neutron diffraction, electronic and thermoelectric transport measurements on a rare-earth-based Kagome compound Tb(Mn,Cr)₆Sn₆. We show that the substitution of Cr into the Mn sites of a Kagome lattice leads to alteration of magnetic structure, which consequently modifies magnetic, electronic, and thermoelectric properties of the system.
