Extended Data Fig. 4

a, ρ(T) curves of La2.79Sr0.21Ni2O7 thin film under various magnetic fields applied perpendicular to the a-b plane of the film. b, Perpendicular upper critical fields extracted by the Tc,90% values (open circles). Solid lines represent Ginzburg-Landau fitting results. c, Electric field (E) versus current density (J) curves measured at 2-20 K.
