We have studied the effect of hydrogen doping on the Hall resistivity of paramagnetic Zr{sub 76}Ni{sub 24}, Zr{sub 40}Ni{sub 60}, Zr{sub 70}Cu{sub 30}, and Zr{sub 60}Cu{sub 40} metallic glasses. All the alloys have positive Hall coefficients except the Zr{sub 40}Ni{sub 60}. The hydrogen dopant increases the absolute value of the Hall coefficient irrespective of its sign, except in the case of (Zr{sub 70}Cu{sub 30}){sub 1{minus}{ital x}}H{sub {ital x}}, where the Hall coefficient decreases for low hydrogen concentrations ({ital x}{lt}0.04) and increases at higher ones, while staying positive all the time. The results are explained as being due to the enhanced {ital s}-{ital d} hybridization.
