(a) Powder X-ray diffraction patterns of the AuxGa85−xDy15 (x = 62–68) iQCs. In all patterns, the peaks can be indexed as those of a primitive icosahedral QC, indicating the formation of highly pure single-phase QCs. The inset shows a selected-area electron diffraction pattern of the Au65Ga20Dy15 QC taken along the fivefold axis. (b) The temperature dependence of the field-cooled magnetic susceptibility (M/H) for the AuxGa85−xDy15 (x = 62, 65 and 68) iQCs. The inset in (b) shows the temperature dependence of Cp/T for the same samples in the range 0 ≤ T ≤ 25 K.
