Figure 4

Magnetic field dependent transport properties of exfoliated BSCCO flakes for the device D3. (a) Zero field four-probe I-V characteristics at 10 K. (Inset) Optical Image for Device D3. Scale bar corresponds to 40 μm. (b) Similar excess current for the two voltage jumps in IVC taken at 10 K. (c) Numerical derivative of IVCs at various B. (d) Colorscale plot of numerical derivative, dV/dI as a function of I, from 0 T to 12 T. Superconductivity is observed even at 12 T magnetic field. All magnetic field measurements were performed at 10 K.
