Sažetak
A study is reported of the heat transport of AlPd(Mn, Fe, Co, Rh) complex metallic alloys that belong to an interesting class of Al-based alloys characterized by giant unit cells with quasicrystal-like cluster substructure. The electrical and thermal conductivity were investigated in the temperature range 8–300 K, in order to see how the exceptional structural complexity and the coexistence of two competing physical length scales affect the transport properties of these materials. The alloys have electrical conductivity typical of metallic alloys, and low thermal conductivity which is at room temperature comparable to that of thermal insulators, e.g. amorphous SiO2 and Zr/YO2 ceramics.
