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…
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…
Insights into ultrafast demagnetization in pseudo-gap half metals
Andreas Mann, Jakob Walowski, Markus Münzenberg +8
Interest in femtosecond demagnetization experiments was sparked by Bigot's discovery in 1995. These experiments unveil the elementary mechanisms coupling the electrons' temperature…
Temperature and bias voltage dependence of Co/Pd multilayer-based magnetic tunnel junctions with perpendicular magnetic anisotropy
Zoë Kugler, Volker Drewello, Markus Schäfers +3
Temperature- and bias voltage-dependent transport measurements of magnetic tunnel junctions (MTJs) with perpendicularly magnetized Co/Pd electrodes are presented. Magnetization mea…
Tunneling spectroscopy probing magnetic and nonmagnetic electrodes in tunnel junctions
Volker Drewello, Zoë Kugler, Günter Reiss +1
Tunneling spectroscopy is applied to tunnel junctions with only one or no ferromagnetic electrode to study the excitation of quasi particles in magnetic tunnel junctions. The bias…
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…
