RESISTIVITY AND SUPERCONDUCTIVITY OF URANIUM BASED METALLIC GLASSES

Amorphous U-Fe, U-Co and U-Ni alloys were prepared by splat quenching over the uranium concentration range of 50 – 83 at%. The temperature dependence of the electrical resistivity, ρ(T), was investigated in the range of 4.2 – 300 K. The results below the Debye temperature (θ ≃ 165 K) may be explained within the frame of the extended Ziman theory and the paramagnon model. The concentration dependence of ρ and of the superconducting transition temperature Tc might be explained by the variation of the d-electron contribution. © 1990, Elsevier Science Publishers B.V.
