title: Orthorhombic tau-Zn-Mg-Dy phase related to a Frank-Kasper type decagonal quasicrystal.
abstract: We report a novel Zn-Mg-Dy phase, denoted as the tau-phase, whose structure is related to that of the Frank-Kasper type decagonal Zn-Mg-Dy phase, based on electron diffraction and high-resolution transmission electron microscopy studies. A plausible atomic model is proposed, which is constructed by two types of atomic clusters related to those in the Zn(7)Mg(4) crystalline compound.
