Bloch-to-Néel domain wall transition evinced through morphology of magnetic bubble expansion in Ta/CoFeB/MgO layers
Arianna Casiraghi, Alessandro Magni, Liza Herrera Diez +5
Ta/CoFeB/MgO trilayers with perpendicular magnetic anisotropy are often characterised by vanishing or modest values of interfacial Dzyaloshinskii-Moriya interaction (DMI), which re…
Investigation of the Dzyaloshinskii-Moriya interaction and room temperature skyrmions in W/CoFeB/MgO thin films and microwires
S. Jaiswal, K. Litzius, I. Lemesh +10
Recent studies have shown that material structures, which lack structural inversion symmetry and have high spin-orbit coupling can exhibit chiral magnetic textures and skyrmions wh…
Ultra-fast perpendicular Spin Orbit Torque MRAM
Murat Cubukcu, Olivier Boulle, Nikolaï Mikuszeit +14
We demonstrate ultra-fast (down to 400 ps) bipolar magnetization switching of a three-terminal perpendicular Ta/FeCoB/MgO/FeCoB magnetic tunnel junction. The critical current densi…
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…
Universal domain wall dynamics under electric field in Ta/CoFeB/MgO devices with perpendicular anisotropy
Weiwei Lin, Nicolas Vernier, Guillaume Agnus +5
Electric field effects in ferromagnetic/oxide dielectric structures provide a new route to control domain wall (DW) dynamics with low power dissipation. However, electric field eff…
Spin-orbit-torque magnetization switching of a three terminal perpendicular magnetic tunnel junction
Murat Cubukcu, Olivier Boulle, Marc Drouard +7
We report on the current-induced magnetization switching of a three-terminal perpendicular magnetic tunnel junction by spin-orbit torque and the read-out using the tunnelling magne…
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…
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…
