High-Field Behavior in the Kondo Effect

Abstract

Third-order perturbation-theory calculations of the conduction-electron scattering in dilute magnetic alloys are examined in the regime ${\ensuremath{\mu}}_{B}H\ensuremath{\gg}k{T}_{K}$, ${T}_{K}$ the Kondo temperature. The results are compared with the high-field resistivity of dilute CuCr alloys, with an $S$-matrix calculation of the field dependence of the Hall coefficient, and with the high-field behavior of the thermopower in AuFe alloys. Suggestions are made for systematic studies in the high-field regime.
