Quantum coherence engineering in the integer quantum Hall regime
P-A. Huynh, F. Portier, H. le Sueur +6
We present an experiment where the quantum coherence in the edge states of the integer quantum Hall regime is tuned with a decoupling gate. The coherence length is determined by me…
Dynamics of two coupled vortices in a spin valve nanopillar excited by spin transfer torque
N. Locatelli, V. V. Naletov, J. Grollier +7
We investigate the dynamics of two coupled vortices driven by spin transfer. We are able to independently control with current and perpendicular field, and to detect, the respectiv…
Coupling efficiency for phase locking of a spin transfer oscillator to a microwave current
B. Georges, J. Grollier, M. Darques +5
The phase locking behavior of spin transfer nano-oscillators (STNOs) to an external microwave signal is experimentally studied as a function of the STNO intrinsic parameters. We ex…
Microwave excitations associated with a wavy angular dependence of the spin transfer torque : model and experiments
O. Boulle, V. Cros, J. Grollier +6
The spin transfer torque (STT) can lead to steady precession of magnetization without any external applied field in magnetic spin valve where the magnetic layer have very different…
Shaped angular dependence of the spin transfer torque and microwave generation without magnetic field
O. Boulle, V. Cros, J. Grollier +6
The generation of oscillations in the microwave frequency range is one of the most important applications expected from spintronics devices exploiting the spin transfer phenomenon.…
High Tc Josephson nanoJunctions made by ion irradiation : characteristics and reproducibility
Jerome Lesueur, Nicolas Bergeal, Martin Sirena +4
Reproducible High Tc Josephson junctions have been made in a rather simple two-step process using ion irradiation. A microbridge 1 to 5 micrometers wide is firstly designed by ion…
