摘　　要：The electronic transport and magnetic perfor- mances of Ni-Nb-Zr metallic glasses under low temperature were investigated. X-ray diffraction （XRD） analysis indicates that the Ni-Nb-Zr ribbons prepared by induction melting and melt spinning method have single amorphous phase. The electrical transport property results of these metallic glass alloys indicate that the Ni-Nb-Zr metallic glasses have negative resistivity temperature coefficients （RTC） and low- temperature drift. The negative RTC and corresponding pos- sible values of Fermi energy of Ni-Nb-Zr metallic glasses are interpreted by the extended Ziman-Faber diffraction theory. The magnetic measurements indicate that the magnetic in- tensities of the Ni-Nb-Zr metallic glasses are related to Ni content and atomic sizes while the low temperature has few influences on the magnetic properties.The electronic transport and magnetic perfor- mances of Ni-Nb-Zr metallic glasses under low temperature were investigated.
