Extended Data Fig. 6: Determination of the critical point where the upturn of Bc2(Jc) occurs.
From: Orbital Fulde–Ferrell–Larkin–Ovchinnikov state in an Ising superconductor
a, An example of I-V measurements at different B|| fields at a fixed temperature. b, The critical current densities Jc were extracted from a. The critical current density is determined as the point where V/I is half the normal resistance RN at T = 10 K. c, The upturn in the B – Jc plot is determined by the kink in dB/dJc.
