Low-Temperature Resistance Anomalies in Iron-Doped V—Cr Alloys

Abstract

There is now considerable evidence1 that interactions between 3d solute atoms in dilute alloys can greatly affect the manifestation of local moment (Kondo) properties. Not only does a maximum appear below the resistance minimum in, for example, Au—Fe when the iron concentration is increased, but more subtle effects are found in almost every system. (In Rh — Fe2 the transition regime from a T 2 to a T behavior moves from ~ 2°K in the dilute limit to below 0.4°K at 0.5% Fe). Striking effects of another kind have for a long time been known to take place in the character of a 3d solute when the host is a binary 4d alloy (e.g., Nb—Mo) and the relative concentration of the two host components is changed. (The classic observation is that of Matthias concerning the influence of iron on superconductivity in that system, and Sarachik et al.3 have demonstrated the associated effects in the electrical resistance.)
