Spin polarized current and Andreev transmission in planar superconducting/ferromagnetic Nb/Ni junctions

E. M. González, A. D. Folgueras, R. Escudero +3

We have measured the tunnelling current in Nb/Nb${}_x$O${}_y$/Ni planar tunnel junctions at different temperatures. The junctions are in the intermediate transparency regime. We have e…
