Extended Data Fig. 7: Three regimes in magnon transport characteristics.

a, G2T averaged over values of VBG on the ν=1 plateau as a function of DC bias. b, VNL/VAC averaged over values of νTG for 0 < νTG < 2. On each plot, the low-, medium- and high-bias regimes are indicated by shading in the same manner as Fig. 3. c, zero-bias measurement of G2T showing a well-developed ν = 0 plateau, implying an insulating ν = 0 ground state as observed in previous transport studies of magnon generation.
