摘要：

We report measurements of the temperature and magnetic field dependence of the resistivity of Ca70Mg15Al15 and Ca70Al30 amorphous alloys, in temperatures down to 0.18 K and fields up to 6 T. The values of B/T are such that we enter a regime where enhanced electron-electron interactions become at least as important as weak localization. Analysis of the data shows that current theories continue to be applicable in those very weak spin-orbit scattering systems, even when B/T is as high as 23 T K-1..AE © 1990 The American Physical Society.
