Sažetak
The electrical resistivity of hydrogen-doped Zr67Co33, metallic glass has been measured at temperatures between 1.7 K and 4.2 K and in magnetic fields up to 9 T for various dopant concentrations. The temperature and magnetic field dependence have been analyzed using the theoretical models of weak-localization and electron-electron interaction in disordered three-dimensional conductors. Doping the samples with hydrogen increases disorder. In a Zr67Co33 system, which becomes superconducting at 2.74 K, hydrogen reduces both the effective electron diffusion constant and the screening of the Coulomb interaction, leading to a decrease in conductivity and suppression of the superconducting transition temperature, The relative contributions of the spin-orbit and the Maki-Thompson interaction to the magnetoresistivity are also depressed.
