Abstract

Clear space group determination of a decagonal quasicrystal has been performed for the first time by convergent-beam electron diffraction (CBED) about Al₇₀Ni₁₅Fe₁₅. The space group of the alloy has been revealed to be noncentrosym- metric P10ra2. The alloy is the first quasicrystal to belong to a noncentrosymmetric space group, and has been found to have a lattice period of 0.4 nm in the direction of the decagonal axis, and to accompany structural modulation waves.
