Sažetak
Magnetoresistivity of (Zr2(3d))1−xHx metallic glasses (where 3d stands for Fe and Co atoms) was investigated for different levels of hydrogen doping (x) in the temperature range from 100 K down to 5 K. Obtained magnetoresistivity is positive due to the strong spin-orbit interaction and well described in the terms of exchange-enhanced spin-splitting contributions to the usual weak-localization term. It was found that (Zr2Fe)1−xHx exhibits a significantly stronger magnetoresis-tivity than (Zr2Co)1−xHx for all measured temperatures and doping levels, which is attributed to the increase in the inelastic spin-scattering rate and the Stoner factor (1−I)−1. The magnetoresistivity of (Zr2(3d))1−xHx exhibits a simple B2 behavior at higher temperatures, providing the information on tau−1 in , and a more complex behavior at low temperatures, which gives the information on the spin-orbit scattering rate (tau−1 so ). It was found that the increase in the doping level reduces tau−1 so indicating a hybridization of hydrogen s-electrons with Zr d-electrons and therefore reducing the spin-orbit interaction.
