Measurements of the low-temperature impurity resistance of dilute Al:Mn and Al:Cr alloys indicate a form ρ(T)=ρ₀[1-(Tθ)²] where θ≈530^∘{}K for Mn and 1200^∘{}K for Cr, and this behavior can be correlated with the high-temperature enhanced Pauli susceptibility of these alloys using the localized spin-fluctuation concept.
