Description
We have measured the spin polarized tunneling conductance of a thin Al/Al2O3/amorphous GdxSi1-x planar tunnel junction at T=25 mK in parallel magnetic field H≤3.0 T. Abrikosov-Gorkov theory is a better model for the thin superconducting Al electrode than previously used Bardeen-Cooper-Schrieffer theory. As the magnetic field is increased, we find the best fit to the data by modelling a transition from a superconductor with gap (α<1) to a gapless superconductor (α>1)
