Abstract

Growth conditions for the preparation of a single Al64Cu23Fe13 icosahedral (I-) quasicrystal with excellent quasicrystallinity were examined using the Czochralski method. The appreciation of the quasicrystallinity of the grown single quasicrystal was performed by X-ray structural analysis. The full widths at half-maximum (FWHM) of the Bragg reflections along 2-, 3- and 5-fold symmetry directions have no Q and Q dependence. Where the Q and Q mean the phason momentum and real scattering vector. Furthermore, peak shifts from ideal Bragg positions were not observed. These means that the grown Al64Cu23Fe13 quasicrystal by the Czochralski method has perfect I-phase structure.
