Abstract

The temperature dependence of the conductivity of Al-Pd-Re quasicrystals can be described by a power law, that is, Δσ(T) ∝ T^α; α is different in low- and high-temperature regimes for high-quality samples. At high temperatures, the conductivity is found to be closely related to the inverse Hall coefficient. The magnetic susceptibility χ_M of Al-Pd-Re quasicrystals is negative. At low temperatures the magnitude of χ_M is seen to decrease quite rapidly with increasing temperature. χ_M(T) between 2 and 400 K can be described well by the following relation: χ_M(T) = χ₀ + aT^-α + bT². The possible origins of each of the terms are discussed in this paper.
