The authors present measurements of the temperature dependence of the upper critical field Hc2 and of the magnetoresistance for V1-xSix superconducting amorphous alloys. Negative deviations from the classical variation of Hc2 in a dirty superconductor are observed related to a positive magnetoresistance due to weak localization in amorphous systems with finite spin-orbit coupling. These deviations can be qualitatively explained through the model recently developed by Coffey, Muttalib, and Levin (1984-5)
