Resistance Change in a Magnetic Field of Single Crystals of Bismuth

The work is a continuation of that of Schneider. Crystals were made from several different samples of bismuth and by two methods. The fractional change in a longitudinal field of about 3,000 gauss is found to be a minimum for 0 orientation and a maximum for 90. The crystals, however, fall into two classes, the reason for which has not been determined. The supposition of any considerable fissures along the cleavage planes appears unlikely
