Domain wall dynamics in ultrathin Au/Co/Au films

Archive ouverte

Kirilyuk, A. | Ferré, J. | Pommier, J. | Renard, D.

International audience. We report on the first direct measurements of the domain wall speed and nucleation rate in ultrathin magnetic films with perpendicular anistropy. Nucleation process becomes dominating over the domain wall motion in higher fields, leading to changes in relaxation magnetization curve. The influence of the sample thickness is briefly discussed.

Magnetization reversal in ultrathin ferromagnetic films with perpendicular anisotropy

Archive ouverte | Kirilyuk, A. | CCSD

International audience. This paper presents a detailed study of the magnetization reversal dynamics in ultrathin cobalt films (tCo = 6-12 Å) sandwiched by gold (111) layers, their magnetic anisotropy being perpendic...

Domain walls in ultrathin ferromagnetic films: Velocity and fractal dimension

Archive ouverte | Kirilyuk, A. | CCSD

International audience. We report on the first measurements of the domain wall (DW) velocity at magnetization reversal as a function of the applied magnetic field in ultrathin ferromagneticAu/Co/Au films with perpen...

Magnetization reversal in ultrathin ferromagnetic films with perpendicular anistropy: Domain observations

Archive ouverte | Pommier, J. | CCSD

International audience. We report on the first observation of magnetic-domain structure during spin reversal under field in ultrathin metallic films with perpendicular anisotropy. The magnetization reversal is eithe...
