The amorphous Y5Ni95 alloy films were hydrogenated bv electrolysis. The dependences of magnetization, resistivity and Hall resistivity on H content were measured respectively for a-Y5Ni95Hx in the temperature range from 1.5K to 400 K. Results show that the average moment at 0 K, the Curie temperature and the temperature coefficient of resistivity decrease with increasing H content. While the high field susceptibility, resistivity and extraordinary Hall coefficient increase quickly. These effects of hydrogen are discussed in terms of the current theories.
