Abstract
Measurements of the electrical conductivity and magnetoconductivity are reported for a series of Cu-Ti-Au metallic glasses in the temperature range 1.5 to 30 K and in fields up to 7 T. We have found that the theories of weak localization and Coulomb interaction give reasonable agreement with experiment in the strong spin-orbit cases (3 at. % Au and 6 at. % Au), but fails to describe moderate scattering (0.5 at. % Au and 1 at. % Au) results.
