Extended Data Fig. 8: Hysteresis as a function of B.

dμ/dn measured as a function of both increasing (red) and decreasing (blue) B at fixed densities. Hysteretic regions are highlighted in yellow. d-e, Hysteresis as a function of density, reproduced from Fig. 3a, d. Overlaid yellow lines indicate ranges over which we observe hysteresis as a function of B. Solid (dashed) lines indicate dμ/dnup − dμ/dndown > 0 (<0), respectively. The ranges of ν and B in which hysteresis occurs are independent of which is swept as the fast axis.
