Sažetak

Systematic analysis of the magnetic susceptibilities for a number of Zr-M glassy alloys (M = Cu, Ni, Co and Fe) and for ternary Zr2(Ni1−xMx)1 glassy alloys with M = Ti, V, Cr, Mn, Fe, Co and Cu has been performed. By combining our data for the magnetic susceptibility and superconducting transition temperature with the literature data for low-temperature specific heat, we have extracted the Pauli susceptibilities (χp) and the Stoner enhancement factors (S) for these alloys. The binary Zr-Cu and Zr-Ni alloys have practically the same S, whereas Zr-Co and ZrFe alloys show larger S which increases in going from Co to Fe. In ternary alloys, χp and S show pronounced maxima centred around M = Mn. For these alloys we also estimated S from the low-temperature magnetoresistivity.
