Abstract

We report measurements of the temperature and magnetic-field dependence of the resistivity in single-phase icosahcdral Al-Cu-Fe alloys between 0.15 and 41 K and fields up to 8.8 T. The data are consistent with the predictions of weak localization and electron-electron-interaction theories, even though the disorder parameter (k F l e ) -1 is larger than one. The spin-orbit scattering and the electron-wave-function dephasing rates are found from a fit of the magnetoresistance
