The electronic transport and magnetic performances 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 lowtemperature drift. The negative RTC and corresponding possible 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 intensities 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.
