Susceptibility of thes−dModel

Abstract

The analogy between the thermodynamics of the $s-d$ model and those of a one-dimensional classical Coulomb gas is exploited to calculate the impurity-spin susceptibility on the computer. The numerical method is a special Monte Carlo procedure first used by Metropolis et al. We find a Curie-Weiss form for the static susceptibility with a Néel temperature of about one-third of the Kondo temperature. We discuss the connection between our results and a recent scaling theory of Anderson, Yuval, and Hamann.
