Abstract

Quasicrystalline samples of various compositions close to Al₆₃Cu₂₅Fe₁₂ have been produced by melt spinning or conventional casting. A slight change in the nominal composition induces a steep increase of the resistivity, ranging from 4600 μμ cm in Al₆₃Cu₂₅Fe₁₂ to 10000 μμ cm in Al_62.5Cu₂₅Fe_12.5. The temperature and magnetic field dependences of the conductivity present peculiar behaviours which can be attributed to strong electron-electron interaction effects as already observed in heavily doped semiconductors on the metallic side of the metal-insulator transition. The temperature dependence of the specific heat at very low temperature can also be analyzed within metal-insulator theories.
