Abstract. A systematic study of electrical resistivity of Hf_100−xFe_x (x = 20,25), Hf_100−xCu_x(x = 30,40,50) and Ti₆₅Cu₃₅ metallic glasses has been done in the temperature range 0.3–290 K, and in magnetic fields B≤5 T. All Hf-base alloys are superconducting with T_c≥0.44 K, which is well above the T_c of pure crystalline Hf (0.13 K). From the initial slopes of the upper critical fields, (dH_c2/dT)_Tc, and resistivities we determined the dressed electronic densities of states, N_γ(E_F), for all alloys. Both T_c and N_γ(E_F) decrease with increasing x (Fe and Cu content). The results are compared with those for corresponding Zr-base metallic glasses and ion-implanted Hf films.
