Large amplitude vortex gyration in Permalloy/BiSe-like heterostructures
P. N. Skirdkov, K. A. Zvezdin, A. D. Belanovsky +4
We consider the excitation of large amplitude gyrotropic vortex core precession in a Permalloy nanodisk by the torques originating from the in-plane microwave current flowing along…
Perfect and robust phase-locking of a spin transfer vortex nano-oscillator to an external microwave source
A. Hamadeh, Nicolas Locatelli, V. V. Naletov +5
We study the synchronization of the auto-oscillation signal generated by the spin transfer driven dynamics of two coupled vortices in a spin-valve nanopillar to an external source.…
Reversal process of a magnetic vortex core under the combined action of a perpendicular field and spin transfer torque
N. Locatelli, A. E. Ekomasov, A. V. Khvalkovskiy +5
In a nanopillar with dipolarly coupled vortices, we present an experimental and simulation study to understand how the interplay between the bias field and spin transfer torque imp…
Temperature dependence of microwave voltage emission associated to spin-transfer induced vortex oscillation in magnetic tunnel junction
P. Bortolotti, A. Dussaux, J. Grollier +7
The temperature dependence of a vortex-based nano-oscillator induced by spin transfer torque (STVO) in magnetic tunnel junctions (MTJ) is considered. We obtain emitted signals with…
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…
Phase locking of vortex based spin transfer oscillators to a microwave current
A. Dussaux, A. V. Khvalkovskiy, J. Grollier +8
Phase locking experiments on vortex based spin transfer oscillators with an external microwave current are performed. We present clear evidence of phase locking, frequency pulling,…
