Fig. 2: Detection of spin-split Fermi-surface pockets with quantum oscillations.

a Isothermal magnetization with dHvA quantum oscillations observed at different temperatures for B||[001]. b Corresponding dHvA signal after subtracting a smooth background. c Temperature dependence of FFT amplitudes for selected peaks illustrated in d. The Fermi-surface pockets with the identified extremal areas are shown in the inset of d. e Overall 3D Fermi-surface pockets combined in the first BZ.
