Spin-polarized tunneling in MgO-based tunnel junctions with superconducting electrodes

We prepared magnetic tunnel junctions with one ferromagnetic and one superconducting Al–Si electrode. Pure cobalt electrodes were compared with a Co–Fe–B alloy and the Heusler compound Co[subscript 2]FeAl. The polarization of the tunneling electrons was determined using the Maki–Fulde model and is d...
