Spin-transfer torque switching below 20 kA/cm in perpendicular magnetic tunnel junctions
Johannes Christian Leutenantsmeyer, Marvin Walter, Steffen Wittrock +4
We demonstrate the reduction of critical spin-transfer torque (STT) switching currents in Co-Fe-B/MgO based magnetic tunnel junctions (MTJ) with perpendicular magnetization anisotr…
Time-resolved measurement of the tunnel magneto-Seebeck effect in a single magnetic tunnel junction
Alexander Boehnke, Marvin Walter, Niklas Roschewsky +6
Recently, several groups have reported spin-dependent thermoelectric effects in magnetic tunnel junctions. In this paper, we present a setup for time-resolved measurements of therm…
Parameter space for thermal spin-transfer torque
Johannes Christian Leutenantsmeyer, Marvin Walter, Vladyslav Zbarsky +10
Thermal spin-transfer torque describes the manipulation of the magnetization by the application of a heat flow. The effect has been calculated theoretically by Jia et al. in 2011.…
