Presentation
Research topics My research topic is magnetism and spintronics of low-dimensional structures, with a special focus on magnetization dynamics of domain walls. I am concerned with fundamental processes, investigated in model systems, for a better understanding. This led me to acquire expertise at the frontier of several areas : experimental and theoretical micromagnetism ; surface magnetism; epitaxial growth particularly for self-organization, chemical synthesis, and associated material science. My main current focus is fundamental aspects in magnetic nanowires or nanotubes, in the field of curvilinear and 3D nanomagnetism and spintronics.
