 note = {The local atomic structure in two types of Tsai-type 1/1 quasicrystal approximants in　the Au-Ge-Yb system were observed using scanning transmission electron microscopy　(STEM). The high-angle annular dark-field (HAADF) imaging method in STEM was　employed to detect the difference in local atomic structure at the cluster centers for both　compounds. Two types of cluster centers were observed in the different compounds: a　tetrahedron with various orientations and a single Yb atom. Furthermore, atomic-resolution　energy-dispersive X-ray spectroscopy showed direct evidence for the presence of a single Yb　atom at the cluster center for the later compound.},
