a Optical micrograph image of the graphene Hall bar (W = 15 μm) and a schematic diagram of the measurement configuration. b Plots of differential resistance ry = dVy/dI at T = 5 K as a function of B for DC currents, I, between 0 (blue) and 140 μA (red) in 14 μA intervals, curves are offset by 0.7 Ω for clarity. Curly brackets indicate the emergence of additional non-equilibrium magneto-oscillations (NEMOs) examined in detail in Figs. 2 and 3. Square brackets labelled SdH indicate Shubnikov–de Haas oscillations and square brackets labelled MF indicate the magnetic focussing peaks.
