Field Dependence of the Anomalous Hall Coefficient in Dilute Magnetic Alloys

Abstract

The anomalous Hall coefficient $R$ of dilute magnetic alloys exhibiting the Kondo effect is calculated in the second Born approximation using the $s\ensuremath{-}d$ exchange model. The variation of $R$ as a function of the magnetic field, for fixed temperature, is studied. Comparisons are made with other theories and recent experimental data.
