Extended Data Fig. 5: Magnetic hysteresis, coercive field and superconducting critical temperature in SC1 in device T3.

a, R_xx as a function of the out-of-plane magnetic field at different n_e and D/ε₀ = 0.985 V nm⁻¹. The curves are shifted vertically for clarity. The dashed horizontal lines indicate the shift of each curve (which corresponds to zero resistance). Orange and blue arrows indicate the coercive fields, which is defined as the closest-to-zero magnetic field, in which R_xx increases rapidly. b, Colour map of R_xx versus T and n_e. c, Summary of the coercive fields and the superconducting T_c at different n_e and D/ε₀ = 0.985 V nm⁻¹. d–f, Same as a–c but for D/ε₀ = 1.015 V nm⁻¹.
