a, b The cross-sectional HAADF STEM images of the TbMn6Sn6 single crystal and the TbMn6Sn6/Au heterostructure (s8). The heterostructure is fabricated by depositing 10 nm Au film on the (001) surface of the TbMn6Sn6 single crystal. c-f The energy-dispersive X-ray spectroscopy (EDS) mappings of Au, Mn, Tb, and Sn elements distribution of the structural region shown in (b). The interface of the TbMn6Sn6/Au heterostructure is marked by a green dashed line.
