Exchange-enhanced weak-localization and electron-electron interaction in amorphous paramagnetic Zr-Fe

The weak-localization and electron-electron interaction theories describe in detail the magnetoresistivity of non-transition-metal amorphous alloys. However, the behavior of transition-metal alloys often deviates significantly from the predicted values, in magnitude and in temperature dependence. In this paper we present magnetoresistivity data for the paramagnetic amorphous Zr-Fe alloys and give the first detailed evidence of exchange enhancement of the spin-splitting contributions to the weak-localization and electron-electron terms
