Femtosecond formation dynamics of the spin Seebeck effect revealed by terahertz spectroscopy
T. S. Seifert, S. Jaiswal, J. Barker +18
Understanding the transfer of spin angular momentum is essential in modern magnetism research. A model case is the generation of magnons in magnetic insulators by heating an adjace…
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…
Terahertz spin currents and inverse spin Hall effect in thin-film heterostructures containing complex magnetic compounds
T. Seifert, U. Martens, S. Günther +20
Terahertz emission spectroscopy of ultrathin multilayers of magnetic and heavy metals has recently attracted much interest. This method not only provides fundamental insights into…
Magnetization dynamics in magnonic structures with different geometries: interfaces, notches and waveguides
M. Mansurova, J. von der Haar, J. Panke +3
The discovery of the ultrafast magnetization dynamics twenty years ago has led to a broad variety of experimental techniques to explore phenomena in magnetic materials with high te…
Pumping laser excited spins through MgO barriers
Ulrike Martens, Jakob Walowski, Thomas Schumann +6
We present a study of the tunnel magneto-Seebeck (TMS) effect in MgO based magnetic tunnel junctions (MTJs). The electrodes consist of CoFeB with in-plane magnetic anisotropy. The…
