Spin polarized tunneling in MgO-based tunnel junctions with superconducting electrodes
Oliver Schebaum, Jagadeesh S. Moodera, Andy Thomas
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 comp…

Tunnel magnetoresistance in alumina, magnesia and composite tunnel barrier magnetic tunnel junctions
Oliver Schebaum, Volker Drewello, Alexander Auge +5
Using magnetron sputtering, we have prepared Co-Fe-B/tunnel barrier/Co-Fe-B magnetic tunnel junctions with tunnel barriers consisting of alumina, magnesia, and magnesia-alumina bil…
