Abstract

Single crystals of the simple icosahedral phase Zn 76 Mg 14 Ho 10 have been grown from the melt. The composition of the melt was selected by differential thermal analysis in combination with scanning electron microscopy and wavelength-dispersive X-ray analysis. The quasicrystals have been characterized by single-crystal and powder X-ray diffraction. The quasilattice constant of the primitive six-dimensional hypercubic lattice is a = 0.5143(2) nm. There is no indication of atomic disorder. Holmium on a primitive icosahedral lattice presents a promising probe for possible quasiperiodic long-range magnetic order.
