Sažetak

We report the experimental results for the electrical conductivity and the thermoelectric power of the complex intermetallic polygrain compound T-Al73Mn27. The electrical conductivity shows the non-metallic behavior, but with finite value in the T = 0 limit, and with unusual √T term appearing at the low temperature. This indicates the existence of an electronic pseudo-gap in the system, whereas more detailed theoretical analysis reveals a non-analytic behavior of the spectral conductivity function in the vicinity of the Fermi energy.
