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…
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…
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…
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.…
Tunnel magnetoresistance in alumina, magnesia and composite tunnel barrier magnetic tunnel junctions
Oliver Schebaum, Volker Drewello, Alexander Auge +5
Using magnetron sputtering, we have prepared Co-Fe-B/tunnel barrier/Co-Fe-B magnetic tunnel junctions with tunnel barriers consisting of alumina, magnesia, and magnesia-alumina bil…
Electric breakdown in ultra-thin MgO tunnel barrier junctions for spin-transfer torque switching
M. Schäfers, V. Drewello, G. Reiss +6
Magnetic tunnel junctions for spin-transfer torque switching were prepared to investigate the dielectric breakdown. The breakdown occurs typically at voltages not much higher than…
