Abstract
An examination of the high-temperature magnetic susceptibility in the mean-random-field approximation gives new information on the interaction mechanism between the impurities in a dilute-magnetic-alloy system. More specifically, the experimental "high"-temperature susceptibilities of Au-Fe, Au-Cr, and Au-Mn are analyzed and found to be in good semiquantitative agreement with theory. A theoretical connection between the high- and low-temperature properties of the alloy system agrees well with experiments on Au-Fe and Au-Cr.
