From: High operating temperature in V-based superconducting quantum interference proximity transistors
Interferometer characterization at T bath = 25 mK (sample-A). (a) Current-voltage I(V b) characteristics measured for some values of the flux Φ generated by the external magnetic field. Inset: enlargement around zero bias of the I(V b) characteristics. The peak around zero bias, with maximum magnitude \(I\simeq \) 280 pA, is the Josephson current flowing through the superconducting probe junction. (b) Measured and (c) theoretical differential conductance as function of voltage bias for Φ values as in (a). (d) Experimental and (e) theoretical color plot of the differential conductance dI/dV versus voltage and magnetic flux.
