Electronic transport and magnetic performance of Ni–Nb–Zr metallic glasses

Abstract

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 low-temperature 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.
