Sažetak
We present results for the magnetic field dependence of the electrical resistivity in hydrogen-doped Zr_68Fe_32 metallic glasses. The undoped sample is paramagnetic down to very low temperatures (< 1 K) because of pronounced spin fluctuations. The observed magnetoresistance is positive and increases with hydrogen concentration. The results have been analyzed using a renormalized expression for the magnetoresistivity which takes into account the exchange enhancement of the spin-splitting contributions (through the Stoner factor) to the usual weak localization and electron-electron interaction terms. The magnetoresistivity enhancement of hydrogen-doped Zr_68Fe_32 has been attributed to the increase of the Stoner factor (1 - I) ^ -1, and of the spin-scattering rate thau_s ^ -1. That increase indicates enhancement of spin fluctuations with hydrogen.
