My PhD work is dedicated to the spin transfer induced self-sustained dynamics of two coupled vortices, in nano-pillars spin-valves structures (Py/Cu/Py). A first...

The field of this thesis is the new diluted magnetic semiconductors (DMS) with the possibility<br />of a high Curie temperature : (Ga,Mn)N and (Zn,Cr)Te....

Magnetoresistive devices are currently used as read heads in hard drives. The context of the miniaturization of magnetic sensors to accommodate the increase in storage...

We report synthesis of a transparent magnetic semiconductor by incorporating Ni in zinc oxide (ZnO) matrix. ZnO and nickel-doped zinc oxide (ZnO: Ni) thin films...

The Kondo effect of these single objects represents a model system to study electron correlations, which are nowadays of importance in relation to the emerging field...

In the manuscript it is presented how the spin-polarized transport across magnetic tunnel junctions (MTJ) is affected by presence of structural defects within the...
