Heat capacity, thermal and electrical conductivity of icosahedral Al63Cu25Fe12 and Al62,5Cu25,5Fe12,5
We resent measurements of electrical and thermal conductivity, and heat capacity of different icosahedral AlCuFe alloys in a wide T-range. Electrical resistvity is in good agreement with data previously reported for the same compositions. Low-temperature thermal properties show several unconventional features such as deviations from the expected Debye law for the lattice specific heat below 10K, a local maximum in phonon thermal conductivity near 1K, which separates a plateau-like regime above 5K from a T2.7 regime between 0.1 and 0.8K.
