Magnetic oscillations Excited by Concurrent Spin Injection from a Tunneling Current and a Spin Hall Current
M. Tarequzzaman, T. Böhnert, M. Decker +9
In this paper, a 3-terminal spin-transfer torque nano-oscillator (STNO) is studied using the concurrent spin injection of a spin-polarized tunneling current and a spin Hall current…
Towards wafer scale inductive characterization of spin transfer torque critical current density of magnetic tunnel junction stacks
Sibylle Sievers, Niklas Liebing, Santiago Serrano-Guisan +12
We explore the prospects of wafer scale inductive probing of the critical current density for spin transfer torque switching of a CoFeB/MgO/CoFeB magnetic tunnel junction…
Magneto-thermoelectric figure of merit of Co/Cu multilayers
X. K. Hu, P. Krzysteczko, N. Liebing +7
The switching of the magnetization configurations of giant magnetoresistance multilayer stacks not only changes the electric and thermal conductivities, but also the thermopower. W…
Unusual angular dependence of tunneling magneto-Seebeck effect
Christian Heiliger, Michael Czerner, Niklas Liebing +4
We find an unusual angular dependence of the tunneling magneto-Seebeck effect (TMS). The conductance shows normally a cosine-dependence with the angle between the magnetizations of…
Tunneling magneto thermocurrent in CoFeB/MgO/CoFeB based magnetic tunnel junctions
Niklas Liebing, Santiago Serrano-Guisan, Patryk Krzysteczko +5
We study the tunneling magneto thermopower and tunneling magneto thermocurrent of CoFeB/MgO/CoFeB magnetic tunnel junctions (MTJ). The devices show a clear change of the thermoelec…
Tunneling magneto thermo power in magnetic tunnel junction nanopillars
N. Liebing, S. Serrano-Guisan, K. Rott +4
We study the tunneling magneto thermo power (TMTP) in CoFeB/MgO/CoFeB magnetic tunnel junction nanopillars. Thermal gradients across the junctions are generated by a micropatterned…
Inductive determination of the optimum tunnel barrier thickness in magnetic tunnelling junction stacks for spin torque memory applications
Santiago Serrano-Guisan, Witold Skowronski, Jerzy Wrona +5
We use pulsed inductive microwave magnetometry to study the precessional magnetization dynamics of the free layer in CoFeB/MgO/CoFeB based magnetic tunnelling junction stacks with…
Parameter dependence of resonant spin torque magnetization reversal
L. Fricke, S. Serrano-Guisan, H. W. Schumacher
We numerically study ultra fast resonant spin torque (ST) magnetization reversal in magnetic tunnelling junctions (MTJ) driven by current pulses having a direct current (DC) and a…
Biased quasi ballistic spin torque magnetization reversal
S. Serrano-Guisan, K. Rott, G. Reiss +3
We explore the fundamental time limit of ultra fast spin torque induced magnetization reversal of a magnetic memory cell. Spin torque precession during a spin torque current pulse…
