Relative Hall coefficient RH(T)/RH(77 K) is plotted as a function of temperature and of magnetic flux density. The purity of specimens was nominally “99.9999 %,” and residual resistivity ratios were 3250, 3550, and 510, for samples 1, 2 and 3, depending on oxidation of Fe impurities and annealing. The presence of defects decreased the RRR values to 270, 625 and 720 for samples 1, 2A, and 2B. Plots of relative Hall coefficients are also given for Ag containing small impurity contents of Au. The variation of the relative characteristic peak Hall coefficient with magnetic induction B is plotted for three different values of residual resistivity ratio (RRR).
