ELECTRONIC BAND-STRUCTURE AND MAGNETIC EFFECTS IN TERNARY ZR-2(NI(1-X)M(X))(1) GLASSY ALLOYS

The electronic and magnetic properties of the amorphous Zr-2(Ni(1-x)M(x))(1) alloys (M=Ti, V, Cr, Mn, Fe, Co, Ni and Cu) have been investigated in the temperature range from 1.5K to 300K. As for the other Zr-3d glassy alloys (3d=Fe, Co, Cu or Ni) the temperature dependence of the electrical resistivity (T greater than or equal to 20K) could be described In terms of the Incipient electron localization. The new features are the pronounced variations of the magnetic and electron-transport properties with M. The origin of these variations are the systematic changes In the electronic band structure of the alloys on going from M=Cu towards M=Ti and the tendency to the formation of localized magnetic moments for M around the middle of 3d-series (M=V, Cr, Mn and Fe). The magnetic interactions strongly suppress the effects of the Incipient localization.
