Relation between the anomalous resistivity and the susceptibility for dilute magnetic alloys

It follows from scattering theory that the anomalous resistivity of dilute magnetic impurities may be written as =A–B cos 2S(/5), whereS is a temperature-dependent spin value. This relation is experimentally verified for various systems whenS undergoes an almost complete compensation fromS_max to zero.
