| 中文摘要 | Electrical-resistivity measurements between 1.5 K and 300 K were performed on the Zr-46.75 Ti-8.25 Cu-7.5 Ni-10 Be-27.5 bulk metallic glasses (BMGs) before and after annealing. Results of the superconducting transition temperature measurements are presented for the BMG Zr-46.25 Ti-8.25 Cu-7.5 Ni-10 Be-27.5. The superconducting critical temperature T-e is 1.84K for the as-prepared metallic glassy sample and 3.76K for the annealed sample at zero magnetic fields. The as-prepared metallic glassy sample exhibits negative temperature coefficient of the resistivity in the temperature range from 5 to 300 K. The negative temperature coefficient of the resistivity of the as-prepared metallic glassy sample can be reasonably understood with the extended Faber-Ziman theory in terms of the diffraction model for metallic glasses if it is assumed that Zr, Ti, Cu, Ni and Be contribute 1.5, 1.5, 0.5, 0.5 and 2 conduction electrons, respectively. The R(T) of the BMG Zr-46.15 Ti-8.25 Cu-7.5 Ni-10 Be-27.5 over the temperature range from 5 to 300 K was analyzed by fitting it to a polynomial using a least-squares procedure. |
