Notes:
As a result of a recent analysis of data on the Hall effect in heavy fermion compounds1 we evaluated the higher-order resonant scattering contributions to the skew scattering of conduction electrons. In the single-site approximation we have calculated the t matrix elements for skew scattering correct to fourth order in the Anderson mixing interaction, i.e., we have neglected pair correlation effects. By including this fourth-order correction in our calculation of the Hall resistivity we find it is positive at high temperatures which is in agreement with data on heavy fermion compounds. Prior calculations of this scattering in these compounds were limited to second order in the mixing interaction above TK, and predicted a negative Hall constant at high temperatures.2 By using a phase shift analysis of the skew scattering we have extended our calculation to the incoherent (single-site) strong coupling regime. In the temperature ranges we considered the Hall resistivity is proportional to the product of the resistivity and magnetic susceptibility. This is in agreement with data on heavy fermion compounds.
