Local spin-susceptibility in disordered alloys II

Abstract

We explore the analogy between a new formulation of the problem of local susceptibility in concentrated alloys and the theory of localization of electronic states in disordered systems. This discussion opens the way to a better description and understanding of the effect of local magnetic properties in disordered systems. In particular, the effect of cluster-cluster interactions and the nature of the magnetic-non magnetic phase transition in alloys is considered. Finally, we discuss the possibility in concentrated alloys of a cluster generalization of the spin glass phase.
