  The magnetoconductivity of quasicrystals is often discussed in the frame of
quantum corrections, namely weak (anti-) localiza-tion and electron-electron
interaction. A premise for both effects is a strong elastic scattering of
conduction electrons. Amorphous and icosahedral phases are discussed as
Hume-Rothery alloys with an electronically induced structural peak at the
diameter of the Fermi sphere. Therefore, both should exhibit quantum
corrections. The preparation of quasicrystalline films via the amorphous route
offers the possibility to compare the magnetoconductivity on samples of
identical composition but different structure. We report on
magnetoconduc-tivity measurements at temperatures between 0.2 K and 22 K and
for magnetic fields up to 16 T. With the exception of the electronic diffusion
constant, amorphous as well as icosahedral Al-Pd-Re films can be described by
nearly the same set of parameters if the samples are well on the metallic side
of the metal-insulator transition.
