Abstract
We report the synthesis of high quality single crystals of BaMnBi2 and investigate the transport properties of the samples. The Hall data reveals electron-type carriers and a mobility mu(5K) =1500cm2/Vs. The temperature dependence of magnetization displays behavior that is different from CaMnBi2 or SrMnBi2 , which suggests the possible different magnetic structure of BaMnBi2. Angle-dependent magnetoresistance reveals the quasi-two-dimensional Fermi surface. A crossover from semiclassical MR-H2 dependence in low field to MR-H dependence in high field is observed in transverse magnetoresistance. Our results indicate the anisotropic Dirac fermion states in BaMnBi2.
