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.
基于电子衍射和高分辨率透射电子显微镜研究,我们报道了一种新型的Zn-Mg-Dy相,记为τ相,其结构与Frank-Kasper型十边形Zn-Mg-Dy相的结构相关。提出了一个合理的原子模型,该模型由与Zn(7)Mg(4)晶体化合物中的原子簇相关的两种原子簇构成。
