Details:
I finished my PhD in december 2001. The subject of my thesis was dedicated to the study of the domain walls magnetoresistance in epitaxial systems and secondly, to the effect of the dipolar interactions on the reversal of the magnetization in high-density arrays of dots. Co nanowires were prepared from epitaxial thin films with large in plane uniaxial anisotropy. This system allows to study the magnetization configurations, the dynamics of the reversal and the domain wall contribution to the magnetoresistance. Thus, varying the film thicknesses, a transition from an asymetrical Bloch wall to an asymetrical Neel wall was observed. The lateral confinement of the thin films generates a redistribution of the energies of the system and the micromagnetic configuration changes in a stripe domain structure.
Recently, I started a post-doc position in Spintec laboratory in Grenoble, France. My research activity is focused on the thermomagnetic recording using a new approach for heating of the media: a balistic transfer of the heat from a AFM tip.
