From: Anomalous quantum oscillations and evidence for a non-trivial Berry phase in SmSb
Landau fan diagram analysis of the Berry phase. a SdH oscillations of samples S2 and S6 of SmSb plotted as a function of 1/B. The oscillations were obtained from the field dependence of the magnetoresistance at 1.8 K up to 32 T, and at 4 K up to 60 T, respectively after subtracting the background contribution. b The 1/B dependence of the valley positions in the SdH measurements. The solid lines show linear fits to the data, which both extrapolate to a non-zero residual value close to n0 = 0.5
