Matching domain wall configuration and spin-orbit torques for very efficient domain-wall motion
A. V. Khvalkovskiy, V. Cros, D. Apalkov +6
In our numerical study, we identify the best conditions for efficient domain wall motion by spin-orbit torques originating from the Spin Hall effect or Rashba effect. We demonstrat…
Vertical current induced domain wall motion in MgO-based magnetic tunnel junction with low current densities
A. Chanthbouala, R. Matsumoto, J. Grollier +11
Shifting electrically a magnetic domain wall (DW) by the spin transfer mechanism is one of the future ways foreseen for the switching of spintronic memories or registers. The class…
Non-uniformity of a planar polarizer as a reason of spin-transfer induced vortex oscillations at zero field
A. V. Khvalkovskiy, J. Grollier, N. Locatelli +3
We discuss a possible mechanism of the spin-transfer induced oscillations of a vortex in the free layer of spin-valve nanostructures, in which the polarizer layer has a planar magn…
Large microwave generation from d.c. driven magnetic vortex oscillators in magnetic tunnel junctions
A. Dussaux, B. Georges, J. Grollier +10
Spin polarized current can excite the magnetization of a ferromagnet through the transfer of spin angular momentum to the local spin system. This pure spin-related transport phenom…
Critical velocity for the vortex core reversal in perpendicular bias magnetic field
Alexey V. Khvalkovskiy, Andrei N. Slavin, Julie Grollier +2
For a circular magnetic nanodot in a vortex ground state we study how the critical velocity of the vortex core reversal depends on the magnitude of a bias magnetic field…
High domain wall velocities due to spin currents perpendicular to the plane
A. V. Khvalkovskiy, K. A. Zvezdin, Ya. V. Gorbunov +3
We consider long and narrow spin valves composed of a first magnetic layer with a single domain wall (DW), a normal metal spacer and a second magnetic layer that is a planar or a p…
