Magnetic and electrical transport properties of MnBi<sub>2</sub>Te<sub>4</sub>
ORAL
Abstract
MnBi2Te4 is considered as an intrinsic antiferromagnetic topological insulator. We have successfully synthesized MnBi2Te4 single crystals. The magnetic susceptibility measurements indicate that the Neel temperature TN = 25 K with the easy axis along the c direction. Below TN, the system undergoes a spin flop transition at Hsf when the magnetic field (H) is applied along the c axis with H > Hsf. The critical field Hsf increases with decreasing temperature, reaching 3.5 Tesla at 2 K. Correspondingly, both the magnetoresistance and Hall resistivity show anomaly at Hsf. Detailed data analysis and implication will be presented.
