Abstract

The electric resistivities (in the temperature range from 8 K to 300 K), the room temperature magnetic susceptibility and the superconducting transition temperature of the amorphous Zr_2(Ni_1-xMx)_1 alloys (M=Ti, V, Cr, Mn, Fe, Co, Ni and Cu) have been investigated. The temperature dependence of the electrical resistivity can be described in terms of the incipient electron localisation effects inherent to the high resistivity alloys, same as of the other Zr-3d glassy alloys (3d=Fe, Co, Cu or Ni). The new features introduced with M are the pronounced nonmonotonic 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 (as confirmed by the photoemission experiments on similar (Zr_67Ni_33)_85M_15 amorphous alloys) and the tendency to the formation of localized magnetic moments for M around the middle of 3d-series (M=V, Cr, Mn and Fe). A novel feature is a rather strong suppression of the effects of the incipient localization in the resistivity by the magnetic interactions.
