Large magneto-Seebeck effect in magnetic tunnel junctions with half-metallic Heusler electrodes
Alexander Boehnke, Ulrike Martens, Christian Sterwerf +9
Spin caloritronics studies the interplay between charge-, heat- and spin-currents, which are initiated by temperature gradients in magnetic nanostructures. A plethora of new phenom…
Enhancement of thermovoltage and tunnel magneto-Seebeck effect in CoFeB based magnetic tunnel junctions by variation of the MgAlO and MgO barrier thickness
Torsten Huebner, Ulrike Martens, Jakob Walowski +7
We investigate the influence of the barrier thickness of CoFeB based magnetic tunnel junctions on the laser-induced tunnel magneto-Seebeck effect. Varying the…
Comparison of laser induced and intrinsic tunnel magneto-Seebeck effect in CoFeB/MgAlO and CoFeB/MgO magnetic tunnel junctions
Torsten Huebner, Alexander Boehnke, Ulrike Martens +5
We present a comparison of the tunnel magneto-Seebeck effect for laser induced and intrinsic heating. Therefore, CoFeB/MgAlO and CoFeB$_{…
Exchange bias effect in martensitic epitaxial Ni-Mn-Sn thin films applied to pin CoFeB/MgO/CoFeB magnetic tunnel junctions
Niclas Teichert, Alexander Boehnke, Anna Behler +3
The exchange bias effect is commonly used to shift the coercive field of a ferromagnet. This technique is crucial for the use of magnetic tunnel junctions as logic or memory device…
Structure and Giant Inverse Magnetocaloric Effect of Epitaxial Ni-Co-Mn-Al Films
Niclas Teichert, Daniel Kucza, Oguz Yildirim +10
The structural, magnetic, and magnetocaloric properties of epitaxial Ni-Co-Mn-Al thin films with different compositions have been studied. The films were deposited on MgO(001) subs…
Physical characteristics and cation distribution of NiFe2O4 thin films with high resistivity prepared by reactive co-sputtering
Christoph Klewe, Markus Meinert, Alexander Boehnke +6
We fabricated NiFe2O thin films on MgAl2O4 (001) substrates by reactive dc magnetron co-sputtering in a pure oxygen atmosphere at different substrate temperatures. The film propert…
