Abstract

We measured the magnetizationM of diluteAu-V alloys of concentration varying between 0.2 and 10 at.% at 4.2 K in fields up to 60 kOe.M is proportional to the field for all fields. The specific heat, measured between 0.4 and 3 K, shows a term linear in temperature γT, with γ=3.3 and 4.6 mJ · mole−1 · K−2 for the 5 and 10% V alloys, respectively. x and γ increase less rapidly than the vanadium concentration. In terms of different “magnetic” character between isolated impurities and nearest neighbors, the analysis of the specific heat results is consistent with a drastic reduction in thed spin susceptibility of V nearest neighbors by interaction effects, contrary to the case ofAu-Co,Cu-Co,Cu-Ni, andCu-Fe where interaction effects produce an enhancement of x. The fluctuation temperature of these two types of impurities is very different;T f ≃270 K for isolated V atoms andT f ≃2500 K for V nearest neighbors. The V atoms in group tend to have the same character as vanadium metal. The observed increase of the ratio ξ=(xdγ/dc)/(γdx/dc) from 0.2 for isolated atoms to 0.8 for V in group is consistent with the decrease of Hund's coupling.
