Fig. 8: The effect of temperature on the superconducting diode effect.
a The dependence of the negative \({I}_{c}^{-}\) (red triangles) and positive \({I}_{c}^{+}\) (blue circles) critical currents on temperature, measured at the magnetic field of −5 μT. At temperature T0 = 0.52 K the diode effect disappears, i.e., \(\eta ={I}_{c}^{-}/{I}_{c}^{+}\) = 1 for T > T0. b The ratio of the negative and positive critical currents versus the temperature. The horizontal axis in (a) and (b) is the same.
