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 classical geometries where the current is injected in the plane of the magn

Spin-momentum transfer between a spin-polarized current and a ferromagnetic layer can induce steady-state magnetization precession, and has recently been proposed as a working principle for ubiquitous radio-frequency devices for radar and telecommuni

We present the influence of post-growth annealing on crystallization process of amorphous CoFeB and tunneling magnetoresistance effect in polycrystalline CoFeB/MgO/CoFeB magnetic tunnel junctions (MTJs). The crystallization of amorphous CoFeB to bcc

Spin torque resonance has been used to simultaneously probe the dynamics of a magnetic domain wall and of magnetic domains in a nanostripe magnetic tunnel junction. Due to the large associated resistance variations, we are able to analyze quantitativ

We measured differential conductance spectra of magnetic tunnel junctions (MTJs) with thin MgO barrier and low-resistance area product. The spectra of MTJs with MgO barrier thicker than 1.05 nm were essentially the same except for slight decrease of

We present time-resolved measurements of the displacement of magnetic domain-walls (DWs) driven by vertical spin-polarized currents in track-shaped magnetic tunnel junctions. In these structures we observe very high DW velocities (600 m/s) at current

We investigated spin-transfer-torque (STT)-induced rf oscillation with a magnetic field applied perpendicular to the plane of CoFeB/MgO/CoFeB magnetic tunnel junctions (MTJs). For the rf measurement with the magnetic field normal to the MTJ plane, th
