Abstract :
We report the results of a comprehensive study of localization and electron–electron interaction effects in Fe-base metallic glasses. We have measured the electrical conductivity and magnetoconductivity within the temperature range 1.8 K≤T≤300 K. A maximum is observed in the conductivity versus temperature curve at temperature T=Tm. The conductivity obeys a T1/2 law for T<Tm and T2 law for T>Tm. Magnetoconductivity data indicate that the electron–electron interaction is most prominent in these alloys at low temperature. From the magneto-conductivity data we have calculated the inelastic scattering field and spin–orbit scattering field. The inelastic scattering field follows a Tp law (p=2) at low temperature.
