Generation of magnonic spin wave traps
Frederik Busse, Maria Mansurova, Benjamin Lenk +2
Spatially resolved measurements of the magnetization dynamics induced by an intense laser pump-pulse reveal that the frequencies of resulting spin wave modes depend strongly on the…
Controlling boron redistribution in CoFeB/MgO magnetic tunnel junctions during annealing by variation of cap layer materials and MgO deposition methods
Henning Schuhmann, Michael Seibt, Volker Drewello +4
Magnetic tunnel junctions with crystalline MgO tunnel barrier and amorphous CoFeB electrodes received much attention due to their high tunnel magneto resistance ratio at room tempe…
On/off switching of bit readout in bias-enhanced tunnel magneto-Seebeck effect
Alexander Boehnke, Marius Milnikel, Marvin Walter +8
Thermoelectric effects in magnetic tunnel junctions are currently an attractive research topic. Here, we demonstrate that the tunnel magneto-Seebeck effect (TMS) in CoFeB/MgO/CoFeB…
Spin-transfer torque switching at ultra low current densities
Johannes Christian Leutenantsmeyer, Vladyslav Zbarsky, Steffen Wittrock +9
The influence of the tantalum buffer layer on the magnetic anisotropy of perpendicular Co-Fe-B/MgO based magnetic tunnel junctions is studied using magneto-optical Kerr-spectroscop…
