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…
Magnetic domain wall motion by spin transfer
Julie Grollier, Andre Chanthbouala, Rie Matsumoto +4
The discovery that a spin polarized current can exert a large torque on a ferromagnet through a transfusion of spin angular momentum, offers a new way to control a magnetization by…
A ferroelectric memristor
André Chanthbouala, Vincent Garcia, Ryan O. Cherifi +10
Memristors are continuously tunable resistors that emulate synapses. Conceptualized in the 1970s, they traditionally operate by voltage-induced displacements of matter, but the mec…
Quantitative MRFM characterization of the autonomous and forced dynamics in a spin transfer nano-oscillator
A. Hamadeh, Grégoire De Loubens, V. V. Naletov +4
Using a magnetic resonance force microscope (MRFM), the power emitted by a spin transfer nano-oscillator consisting of a normally magnetized PyCuPy circular nanopillar is mea…
