抄録

The structure of a W- (AlCoNi) approximant phase allows us to discuss a local atomic arrangement for a variety of Al-Co-Ni decagonal phases, by serving an ideal frame of the pentagonal columnar structure of 2 nm in diameter. The present approach also demonstrates that the combinatory analysis of the single crystal X-ray diffraction coupled with electron microscopy such as HAADF-STEM and HRTEM is one of powerful tools for the structural analysis of complicated structures.
