Maître de Conférences (Assistant Professor) at Université Grenoble Alpes
The research projects of J. P. Attané focus on new ways to change the orientation of magnetization using currents, which could lead to new generations of spintronic devices. These projects can be divided in two parts. The first part is focused on the interaction of polarized currents with the magnetization, and includes :
The second part consists in generating, detecting and using pure spin currents, which corresponds to the case where up and down spins goes along opposite directions, whereas there is no charge current. Such currents might allow the development of a new spintronics without ferromagnets. This second part involves :

J. P. Attané obtained his PhD in Solid State Physics from Joseph Fourier University (Grenoble) in 2003 on the topic of magnetization reversal in thin layers with perpendicular anisotropy. After a post-doc in Burkard Hillebrand’s group at Kaiserslautern University (from 2003 to 2004), he has been recruited in 2004 as Assistant Professor (Maitre de Conférences) at Joseph Fourier University (Grenoble).
Since his recruitment in 2004, he developped a research team whose activities focus on the study of domain-wall propagation in nanostructures, and of spin-dependent transport phenomena in nanostructures. He is now leading this team, which in the recent years was composed of around 6-8 full-time equivalent people.
His scientific work awarded him to be admitted in 2011 as a member of the "Institut Universitaire de France", and he obtained his "Habilitation à Diriger des Recherches" in 2012.
We are currently looking for PhD students or M2 internships (eventually M1 internships) on the two following subjects :
