Electronic structure of (Ni33Zr67)1 − 1Xx (X ≡ Ti, V, Cr, Mn, Fe, Co, Ni or Cu) ternary metallic glasses studied by low temperature specific heat measurements

Abstract

Low temperature specific heats were measured on a total of 35 (Ni₃₃Zr₆₇)_{1 − x}X_x (0 ⩽ x ⩽ 0.25) ternary metallic glasses, where X is any 3d transition metal from titanium to copper, over the temperature range 1.5–6 K. The magnetic specific heat is found to be superimposed on the ordinary contributions in the alloys containing manganese and iron. Except for these magnetic alloys, the variation in the density of states at F_F on adding the third element can be deduced from the measured electronic specific heat coefficient. The results can be explained on the basis of the UV photoelectron spectra measured on the same series of samples.
