Abstract

The change of the low-field Hall coefficient RoH of polycrystalline aluminum due to the addition of 3d transitional impurities Ti, Cr, Mn, Fe, Ni and Cu is measured at 4.2 K. The results show that RoH depends systematically on the valence of the impurities, and has the lowest value for chromium. An analysis of the results is given using a three group model of the Fermi surface of Al and the Friedel-Anderson model for a localized virtual bound state.
