Anomalous Transport Properties in Pure AlCuFe Icosahedral Phases of High Structural Quality

Abstract: A very high-resistivity value ( p 4 ~-4300 p*ncm>, associated to a strong negative temperature dependence (a = l/p 1 &/AT --K-'), is measured in pure icosahedral A163C~25Fe12 phases (a single grain and polyq&erystalline samples). Moreover the resistivity of the defective as-quenched ~A&$2u25Felz samples is much smaller ( p 4 ~ -1300 yQcm) and increases sharply (up to -4300pQcm) after annealing treatment. We show also that the temperature and magnetic-field dependences of the resistivity and the Hall effect can… Show more

“…Accordingly we assume icosahedral quasicrystals to be semiconductors with complex band structures, which are essentially determined by electron-phonon interactions as in icosahedral boron-rich structures. This conclusion is consistent with the results of dc measurements of icosahedral quasicrystals (8)(9)(10)(11)(12).…”

“…One well-known, remarkable property of many quasicrystals is that increased atomic disorder leads to decreased resistivity [29]. This has long been expected also for i-AlPdRe, and was shown recently by structural and transport studies of samples irradiated with high energy neutrons [26].…”

“…Therefore, the lowtemperature and magnetic-field dependencies of the electrical conductivity in QC's have been usually analyzed in terms of quantum interference effects. 16,19,22,24,25,50 These theories were elaborated for metals in the weak disorder limit. Thus, it is intriguing how concepts originally developed to describe amorphous solids can be successful in describing long-range ordered systems such as QC's.…”
