摘要

Two icosahedral Al Pd Mn samples extracted from the same Czochralskigrown single quasicrystal have been studied by high-resolution synchrotron X-ray diffraction. While the first sample had an almost planar surface resulting from cleavage, the second had a planar surface obtained by mechanical polishing. In Q both samples the width of the diffraction peak profiles increases linearly with , per the perpendicular component of the six-dimensional reciprocal lattice vector. However, the broadening is larger in the polished sample, indicating that phason strain has been introduced during the polishing process.
