a Normalized magneto-thermopower, Sxx(B)/Sxx(0T), measured at different temperatures. The three orange down-triangles indicate the splitting of the n = 1 peak. b Oscillatory component ΔSxx as a function of 1/B at 2.3 K, obtained by subtracting a linear background from Sxx. Inset: The n = 0 peak obtained by reference to the high-temperature data at 50 K, Sxx(2.3 K)/Sxx(50 K). c Landau fan diagram of the magneto-thermopower oscillations at 2.3 K. The peak features in b are separated into two groups depending on the splitting mechanism and labeled by the red and blue down-triangles, respectively. The dash lines indicate the average positions of additional splittings in the n = 1 LL, and the solid lines are linear fits to the data of each group.
