Thermomagnetic figures of merit of bismuth at 77 K

The thermomagnetic figures of merit of bismuth for different crystallographic orientations have been measured at 77°K for magnetic fields up to 12 kOe. The magnetoresistance ratios were also determined for fields of 10 kOe. The experimental results for the high-field figure of merit are consistent with theoretical calculations based on Abeles and Meiboom's model for the band structure of bismuth.
