Sažetak
Thermal, K(T), and electrical conductivity, s(T), measurements of the polygrain icosahedral quasicrystal i-Al72Pd19.5Mn8.5 are reported in the temperature range 10 K- 300 K. Electrical conductivity shows an anomalous behavior with a minimum at 120 K and the room temperature value sR.T. = 83000 W-1m-1. Thermal conductivity at room temperature is KR.T. = 3.4 W/mK, and by lowering the temperature K(T) shows a broad minimum at 120 K, and a shallow maximum around 30 K. The temperature behaviour of thermal conductivity is explained by the Debye model in the temperature range below 50 K, and in the frame of the variable range hopping model above 120 K.
