Fig. 6: Experimental-theoretical comparison of quantum oscillations.

a Magnetic torque data taken at high field on sample S3 for field applied along raw data for B ∥ [011] (orange) and the a-axis (purple, amplitude increased five times). b Quantum oscillation frequency spectra of the data in (a). Peaks marked with Greek letters correspond to those found at similar frequencies (±100 T) and the same angle in a prior quantum oscillation study38, using the notation of that work. A peak not identified in the previous study is labeled with an asterisk. c A comparison of observed fundamental quantum oscillation frequencies (red dots) to predicted electron (green lines) and hole (blue lines) band oscillation frequencies for EF = +0.15 meV generated by SKEAF calculations for rotation between the angles in (a) and (b) of S3. d A comparison of SKEAF-generated frequencies from the same FS to data from Nozue et al.38 for field rotated between the a- and b-axes.
