چکیده انگلیسی
Magnetoresistivity of (Zr2(3d))1 â xHx metallic glasses (where 3d stands for Fe and Co atoms) was investigated as a function of hydrogen doping (x) in the temperature range from 100 K down to 5 K. Obtained magnetoresistivity is always 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. (Zr2Fe)1 â xHx exhibits a significantly stronger magnetoresistivity than (Zr2Co)1 â xHx for all measured temperatures and doping levels, which is attributed to the increase in the inelastic spin-scattering rate (Ïinâ 1) and the Stoner factor (1 â I)â 1. The magnetoresistivity of (Zr2(3d))1 â xHx exhibits a simple B2 behavior at higher temperatures, providing the information on Ïinâ 1, and a more complex behavior at low temperatures, which gives the information on the spin-orbit scattering rate (Ïsoâ 1). It was found that the increase in the doping level reduces Ïsoâ 1, indicating hybridization of hydrogen s-electrons with Zr d-electrons and thus reducing the spin-orbit interaction.
