摘要

The structure of a Cd_(68)Mg_(12)Dy_(20) crystalline phase denoted as the φ-phase, which has a composition close to that of the Cd_(66)Mg_(21)Dy_(13) icosahedral quasicrystalline phase, has been investigated by electron diffraction and scanning transmission electron microscopy (STEM). The φ phase has a fcc lattice with a = 21.6 A. High-angle annular dark-field STEM with Z contrast confirms that the phase has the Cd_(45)Sm_(11)-type structure. The atomic cluster in the structure is shown to be characterized by a Friauf polyhedron with tetrahedral symmetry.
