The goal of this PhD was to study magnetisation dynamics in two perpendicularly magnetised nano-systems; metallic Pt/Co(5 Å)/Pt and the diluted ferromagnetic semiconductor GaMnAs. Magnetisation reversal, under the action of a magnetic field in nano-dots or the spin polarised current induced domain wall motion in a track, has been studied using polar Kerr magneto-optics. Nano-structuration was realised by classical eching to obtain GaMnAs nano-dots and tracks and by an elegant process in the ultrathin cobalt layer case: helium ion irradiation which yields nano-dots in a planar and paramagnetic environment. For these two systems, with different ferromagnetism and anisotropy origins, the lateral confinement implies a transition from a multi-mo...
