The temperature dependence of the Hall effect in the range 6-80 K has been determined in monocrystalline samples having $\overrightarrow{\mathrm{H}}$ along principal crystallographic directions. Samples of Au and of Cu containing Fe, Mn, or Ni (4-24 at. ppm) were studied in experiments encompassing the intermediate-field condition. These data for monocrystals are compared with those obtained in earlier work for Cu and Cu containing Zn. The comparison supports the validity of the earlier qualitative interpretation of the temperature dependence, and also shows how a more detailed understanding of the behavior observed in polycrystals can be obtained from the observed changes in behavior of the various contributing cyclotron orbits as solute is added.
