| dc.description.abstract | We have studied the magnetotransport properties of a topological crystalline insulator, SnxPb1-xTe with the applied fields up to 14 T. Magnetoresistance (MR) increases almost linearly with the applied field and reaches a value of 310% at H = 13 T without showing any sign of saturation. At higher applied fields, both longitudinal and Hall resistance show clear Shubnikov de Haas (SdH) oscillations with a single oscillation frequency at α = 57 T. However, an additional frequency at β = 69 T appears if the angle between the field direction and the sample surface is changed. Using the quantum oscillations data, we have constructed the Landau-level fan diagram and determined the trivial topology of the α-pocket. The obtained results are compared with the previous reports and the possible origin of the second frequency (β) will be discussed. | en_US |
