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 investiga ted 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 desc ribed In terms of the Incipient electron localization. The new feature s 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 magnet ic moments for M around the middle of 3d-series (M=V, Cr, Mn and Fe). The magnetic interactions strongly suppress the effects of the Incipie nt localization.
