Electrical resistivities of several quasicrystalline (QC) icosahedral Al-Cu-Ru alloys have been measured between room temperature and mK temperatures. None of the Al-Cu-Ru samples exhibited "insulating" behaviors in their resistivities. One sample had a large resistivity of ≈49,000 μΩ cm at room temperature. Its resistivity increased with decreasing temperatures by a factor of 3.2 and exhibited a maximum around 2 K. Fitting discrepancies between the experimental magnetoconductivity data and the weak localization and electron-electron interaction theories suggest that the weak localization theory poorly describes the electronic conduction behavior of this highly resistive quasicrystalline sample.
