Interesting behavior of magnetoresistance in single crystals of CeBi*

Cerium monopnictides, CeX (X= Sb, Bi) have gained renewed interest as potential candidates to host non-trivial topological band structure along with magnetism. High quality single crystals of CeBi were grown out of Bi self-flux. Systematic measurements of temperature and magnetic field dependent resistivity and magnetization were conducted on CeBi. A rich H-T phase diagram was mapped out. Interestingly, extremely large magnetoresistance was observed at low temperature, and large negative magnetoresistance was detected at the intermediate temperature regime. To obtain a better understanding of the system, the electronic structure is also being studied.
