Metallic Phase with Long-Range Orientational Order and No Translational Symmetry
Phys. Rev. Lett. 53, 1951 – Published 12 November, 1984
DOI: https://doi.org/10.1103/PhysRevLett.53.1951
Abstract
We have observed a metallic solid (Al-14-at.%-Mn) with long-range orientational order, but with icosahedral point group symmetry, which is inconsistent with lattice translations. Its diffraction spots are as sharp as those of crystals but cannot be indexed to any Bravais lattice. The solid is metastable and forms from the melt by a first-order transition.
