Magnetoresistance of heavy and light metal/ferromagnet bilayers
Can Onur Avci, Kevin Garello, Johannes Mendil +6
We studied the magnetoresistance of normal metal (NM)/ferromagnet (FM) bilayers in the linear and nonlinear (current-dependent) regimes and compared it with the amplitude of the sp…
Spin-orbit torque driven chiral magnetization reversal in ultrathin nanostructures
N. Mikuszeit, O. Boulle, I. M. Miron +4
We show that the spin-orbit torque induced magnetization switching in nanomagnets presenting Dzyaloshinskii-Moriya (DMI) interaction is governed by a chiral domain nucleation at th…
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…
Unidirectional spin Hall magnetoresistance in ferromagnet/normal metal bilayers
Can Onur Avci, Kevin Garello, Abhijit Ghosh +3
Magnetoresistive effects are usually invariant upon inversion of the magnetization direction. In noncentrosymmetric conductors, however, nonlinear resistive terms can give rise to…
