We report transport measurements in a Al/Al2O3/Co junction of intermediate quality with an Al electrode of moderate thickness. Current-voltage curves of the junctions are recorded at different temperatures and different magnetic fields. The measured conductance spectra are compared with predictions of the polarized BTK model and with a simple extension of the model accounting for a finite applied magnetic field.

Abstract
We report transport measurements in a Al/Al2O3/Co junction of intermediate quality with an Al electrode of moderate thickness. Current-voltage curves of the junctions are recorded at different temperatures and different magnetic fields. The measured conductance spectra are compared with predictions of the polarized BTK model and with a simple extension of the model accounting for a finite applied magnetic field.File in questo prodotto:
