Point-contact (PC) spectra (solid lines) measured in different magnetic fields, indicated on each curve, of an contact characterized by a relatively large order parameter value . The BTK fits are shown by the dashed lines (, ). For clarity, the curves are shifted vertically.
Magnetic field dependence of the gap parameter (solid squares) as compared to the Ginzburg–Landau theory (dashed line) for the contact presented in Fig. 1.
Magnetic field set of the PC spectra (solid lines) for contact with a small order parameter value (, ). The dashed lines present the BTK fits.
The experimental dependence (unfilled circles) in comparison with the Ginzburg–Landau law tied to the first low-field experimental points (dashed lines) for the contact presented in Fig. 3.
Zero-bias differential resistance versus magnetic field dependences measured at different temperatures for an contact with (for clarity the curves are shifted vertically). The values were taken at the points of maximum curvature, as is indicated on the curve by an arrow. The inset shows the PC spectrum of this contact measured in zero magnetic field at (solid line), and the BTK fitted curve.
phase diagram for constructed on the basis of data derived from Fig. 5 (unfilled circles) and fitted to the quadratic law (solid line). The solid squares and dashed line present the data and quadratic fit to them, respectively, reproduced from Ref. 1.
