Abstract

Measurements of magnetoresistance of single crystals of bismuth doped with tin and lead in the temperature range 100 K to 300 K are reported. Both tin and lead have a marked effect in changing the band structure of bismuth. Temperature variations show that with the increased concentration of impurity, Dr/r0 is less dependent on temperature, and the magnetic field variation of Dr/r0 does not obey the quadratic dependence on magnetic field strength.

Keywords

magnetoresistance; single crystals of bismuth doped with tin and lead; temperature and the magnetic field variation; deviation from quadratic dependence on magnetic field strength
