Abstract
Measurements of the Hall coefficient and transverse magnetoresistance have been made on antimony single crystals at liquid helium temperatures and in magnetic fields up to 25 kilogauss. Both these properties exhibit oscillations which are periodic in reciprocal magnetic field. For a given orientation of the crystal axes relative to the magnetic field, the period of oscillation is the same for both these galvanomagnetic effects. The observed periods are in good agreement with the values found in the de Haas-van Alphen effect of antimony. The magnetic field dependence of the Hall coefficient was also examined at 78°K and 300°K. It was found that at 78°K the Hall coefficient already exhibits marked field dependence. Small amounts of impurities were found to have a marked effect on both the magnitude and field dependence of the Hall coefficient at low temperatures.
