Thermal Conductivity of Oxide Tunnel Barriers in Magnetic Tunnel Junctions Measured by Ultrafast Thermoreflectance and Magneto-optic Kerr Effect Thermometry
Hyejin Jang, Luca Marnitz, Torsten Huebner +3
Spin-dependent charge transport in magnetic tunnel junctions (MTJs) can be manipulated by a temperature gradient, which can be utilized for spintronic and spin caloritronic applica…
Thermal conductivity of thin insulating films determined by tunnel magneto-Seebeck effect measurements and finite-element modeling
Torsten Huebner, Ulrike Martens, Jakob Walowski +4
In general, it is difficult to access the thermal conductivity of thin insulating films experimentally just by electrical means. Here, we present a new approach utilizing the tunne…
Correlation of tunnel magnetoresistance with the magnetic properties in perpendicular CoFeB-based junctions with exchange bias
Orestis Manos, Panagiota Bougiatioti, Denis Dyck +4
We investigate the dependence of magnetic properties on the post-annealing temperature/time, the thickness of soft ferromagnetic electrode and Ta dusting layer in the pinned electr…
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$_{…
