Current voltage characteristics as a function of magnetic field and temperature for a typical junction after thermal cycling. a IVCs of a second device (w = 500 nm and L = 100 nm) are shown as a function of B after thermal cycling. The curves are shifted in voltage by a value proportional to the magnetic field. The green points represent the magnetic pattern of the junctions obtained using a voltage criterium V = 600 nV. Also in this case the magnetic pattern presents a very pronounced dip at B = 0. b Evolution of the magnetic pattern shown in a as a function of the temperature. The dip flattens out at a temperature close to 100 mK
